Section 171 A Model for Reaction Rates

One of the most spectacular chemical reactions the one between liquidhydrogen and liquid oxygen provides the energy to launch rockets intospace as shown on the opposite page This reaction is fast and exothermicYet other reactions and processes yoursquore familiar with such as the hardeningof concrete or the formation of fossil fuels occur at considerably slowerrates The DISCOVERY LAB for this chapter emphasized that the speed atwhich a reaction occurs can vary if other substances are introduced into thereaction In this section yoursquoll learn about a model that scientists use todescribe and calculate the rates at which chemical reactions occur

Expressing Reaction RatesAs you know some chemical reactions are fast and others are slow howev-er fast and slow are inexact relative terms Chemists engineers medicalresearchers and others often need to be more specific

Think about how you express speed or rate in the situations shown inFigure 17-1 on the next page The speed of the sprinter on the track teammay be expressed as meters per second The speed at which the hiker movesmight be expressed differently perhaps as meters per minute We generallydefine the average rate of an action or process to be the change in a givenquantity during a specific period of time Recall from your study of math thatthe Greek letter delta () before a quantity indicates a change in the quanti-ty In equation form average rate or speed is written as

For chemical reactions this equation defines the average rate at whichreactants produce products which is the amount of change of a reactant in agiven period of time Most often chemists are concerned with changes in themolar concentration (molL M) of a reactant or product during a reactionTherefore the reaction rate of a chemical reaction is stated as the change inconcentration of a reactant or product per unit time expressed as mol(Ls)Brackets around the formula for a substance denote the molar concentrationFor example [NO2] represents the molar concentration of NO2

Itrsquos important to understand that reaction rates are determined experimen-tally by measuring the concentrations of reactants andor products in anactual chemical reaction Reaction rates cannot be calculated from balancedequations as stoichiometric amounts can

Suppose you wish to express the average rate of the reaction

CO(g) NO2(g) 0 CO2(g) NO(g)

during the time period beginning at time t1 and ending at time t2 Calculatingthe rate at which the products of the reaction are produced results in a reac-tion rate having a positive value The rate calculation based on the produc-tion of NO will have the form

Average reaction rate [

For example if the concentration of NO is 000M at time t1 000 s and0010M two seconds after the reaction begins the following calculationgives the average rate of the reaction expressed as moles of NO produced perliter per second

Alternatively you can choose to state the rate of the reaction as the rate atwhich CO is consumed as shown below

Average reaction rate [

Do you predict a positive or negative value for this reaction In this case anegative value indicates that the concentration of CO decreases as the reac-tion proceeds

Actually reaction rates must always be positive When the rate ismeasured by the consumption of a reactant scientists commonly apply anegative sign to the calculation to get a positive reaction rate Therefore thefollowing form of the average rate equation is used to calculate the rate ofconsumption

The Collision TheoryYou have learned that reaction rates are calculated from experimental dataBut what are we actually measuring with these calculations Looking atchemical reactions from the molecular level will provide a clearer picture ofexactly what reaction rates measure

Have you ever seen a demolition derby in which the competing vehiclesare constantly colliding Each collision may result in the demolition of one ormore vehicles as shown in Figure 17-2a The reactants in a chemical reactionmust also come together in order to form products as shown in Figure 17-2bThe collision theory states that atoms ions and molecules must collide inorder to react The collision theory summarized in Table 17-2 explains whyreactions occur and how the rates of chemical reactions can be modified

Consider the reaction between hydrogen gas (H2) and oxygen gas (O2)

2H2 O2 0 2H2O

According to the collision theory H2 and O2 molecules must collide in orderto react and produce H2O Now look at the reaction between carbon monox-ide (CO) gas and nitrogen dioxide (NO2) gas at a temperature above 500 K

CO(g) NO2(g) 0 CO2(g) NO(g)

These molecules collide to produce carbon dioxide (CO2) gas and nitrogenmonoxide (NO) gas However detailed calculations of the number of molec-ular collisions per second yield a puzzling resultmdashonly a small fraction ofcollisions produce reactions In this case other factors must be considered

Orientation and the activated complex Why donrsquot the NO2 and COmolecules shown in Figure 17-3a and b react when they collide Analysisof this example indicates that in order for a collision to lead to a reaction thecarbon atom in a CO molecule must contact an oxygen atom in an NO2 mol-ecule at the instant of impact Only in that way can a temporary bondbetween the carbon atom and an oxygen atom form The collisions shown inFigure 17-3a and b do not lead to reactions because the molecules collidewith unfavorable orientations That is because a carbon atom does not con-tact an oxygen atom at the instant of impact the molecules simply rebound

When the orientation of colliding molecules is correct as Figure 17-3cillustrates a reaction occurs as an oxygen atom is transferred from an NO2molecule to a CO molecule A short-lived intermediate substance is formedThe intermediate substance in this case OCONO is called an activated com-plex An activated complex is a temporary unstable arrangement of atomsthat may form products or may break apart to re-form the reactants Becausethe activated complex is as likely to form reactants as it is to form productsit is sometimes referred to as the transition state An activated complex isthe first step leading to the resulting chemical reaction

Activation energy and reaction The collision depicted in Figure 17-3ddoes not lead to a reaction for a different reason Although the CO and NO2molecules collide with a favorable orientation no reaction occurs becausethey collide with insufficient energy to form the activated complex The min-imum amount of energy that reacting particles must have to form the acti-vated complex and lead to a reaction is called the activation energy Ea

Activation energy has a direct influence on the rate of a reaction A highEa means that relatively few collisions will have the required energy to pro-duce the activated complex and the reaction rate will be low On the otherhand a low Ea means that more collisions will have sufficient energy toreact and the reaction rate will be higher The problem-solving LAB belowemphasizes this fact It might be helpful to think of this relationship in termsof a person pushing a heavy cart up a hill If the hill is high a substantialamount of energy and effort will be required to move the cart and it will takea long time to get it to the top If the hill is low less energy will be requiredand the task will be accomplished faster

Figure 17-4 shows the energy diagram for the progress of the reactionbetween carbon monoxide and nitrogen dioxide Does this energy diagramlook somewhat different from those you studied in Chapter 16 Why Inaddition to the energies of the reactants and products this diagram shows theactivation energy of the reaction Activation energy can be thought of as abarrier the reactants must overcome in order to form the products In thiscase the CO and NO2 molecules collide with enough energy to overcome thebarrier and the products formed lie at a lower energy level Do you recall thatreactions that lose energy such as this example are called exothermic reactions

For many reactions the process from reactants to products is reversibleFigure 17-5 shows the reverse endothermic reaction between CO2 and NOto reform CO and NO2 In this reverse reaction the reactants which are themolecules that were formed in the exothermic forward reaction lie at a lowenergy level and must overcome a significant activation energy to reform COand NO2 This requires an input of energy If this reverse reaction isachieved CO and NO2 again lie at a high energy level

The influence of spontaneity Recall from Chapter 16 that reaction spon-taneity is related to change in free energy G If G is negative the reac-tion is spontaneous under the conditions specified If G is positive thereaction is not spontaneous Letrsquos now consider whether spontaneity has anyeffect on reaction rates Are more spontaneous reactions faster than lessspontaneous ones

To investigate the relationship between spontaneity and reaction rate con-sider the following gas-phase reaction between hydrogen and oxygen

2H2(g) O2(g) 0 2H2O(g)

Here G 458 kJ at 298 K (25degC) and 1 atm pressure Because G isnegative the reaction is spontaneous For the same reaction H 484 kJ which means that the reaction is highly exothermic You canexamine the speed of this reaction by filling a tape-wrapped soda bottle withstoichiometric quantities of the two gasesmdashtwo volumes hydrogen and onevolume oxygen A thermometer in the stopper allows you to monitor thetemperature inside the bottle As you watch for evidence of a reaction thetemperature remains constant for hours Have the gases escaped Or havethey simply failed to react If you remove the stopper and hold a burningsplint to the mouth of the bottle a reaction occurs explosively Clearly thehydrogen and oxygen gases have not escaped from the bottle Yet they didnot react noticeably until you supplied additional energy in the form of alighted splint The example shown in Figure 17-6 illustrates this same phe-nomenon The soap bubbles you see billowing from the bowl are filled withhydrogen When the lighted splint introduces additional energy an explo-sive reaction occurs between the hydrogen that was contained in the bub-bles and oxygen in the air

As these examples show reaction spontaneity in the form of G impliesabsolutely nothing about the speed of the reaction G merely indicates thenatural tendency for a reaction or process to proceed Factors other thanspontaneity however do affect the rate of a chemical reaction These factorsare keys in controlling and using the power of chemistry

According to the collision theory chemical reactions occur when moleculescollide in a particular orientation and with sufficient energy to achieve acti-vation energy You can probably identify chemical reactions that occur fastsuch as gasoline combustion and others that occur more slowly such as ironrusting But can the reaction rate of any single reaction vary or is the reac-tion rate constant regardless of the conditions In this section you will learnthat the reaction rate for almost any chemical reaction can be modified byvarying the conditions of the reaction

The Nature of ReactantsAn important factor that affects the rate of a chemical reaction is the reactivenature of the reactants As you know some substances react more readily thanothers For example calcium and sodium are both reactive metals howeverwhat happens when each metal is added to water is distinctly different Whena small piece of calcium is placed in cold water as shown in Figure 17-7athe calcium and water react slowly to form hydrogen gas and aqueous calci-um hydroxide

Ca(s) 2H2O(l) 0 H2(g) Ca(OH)2(aq)

When a small piece of sodium is placed in cold water the sodium and waterreact quickly to form hydrogen gas and aqueous sodium hydroxide as shownin Figure 17-7b

2Na(s) 2H2O(l) 0 H2(g) 2NaOH(aq)

Comparing the two equations itrsquos evident that the reactions are similarHowever the reaction between sodium and water occurs much fasterbecause sodium is more reactive with water than calcium is In fact the reac-tion releases so much heat so quickly that the hydrogen gas ignites as it isformed

ConcentrationReactions speed up when the concentrations of reacting particles areincreased One of the fundamental principles of the collision theory is thatparticles must collide to react The number of particles in a reaction makes adifference in the rate at which the reaction takes place Think about a reac-tion where reactant A combines with reactant B At a given concentration ofA and B the molecules of A collide with B to produce AB at a particular rateWhat happens if the amount of B is increased Increasing the concentrationof B makes more molecules available with which A can collide Reactant Aldquofindsrdquo reactant B more easily because there are more B molecules in thearea which increases probability of collision and ultimately increases therate of reaction between A and B

Look at the two reactions shown in Figure 17-8 Steel wool is first heat-ed over a burner until it is red hot In Figure 17-8a the hot steel wool reactswith oxygen in the air How does this reaction compare with the one inFigure 17-8b in which the hot steel wool is lowered immediately into a flaskcontaining nearly 100 percent oxygenmdashapproximately five times the concen-tration of oxygen in air Applying the collision theory to this reaction thehigher concentration of oxygen increases the collision frequency betweeniron atoms and oxygen molecules which increases the rate of the reaction

If you have ever been near a person using bottled oxygen or seen an oxy-gen generator you may have noticed a sign cautioning against smoking orusing open flames Can you now explain the reason for the caution noticeThe high concentration of oxygen could cause a combustion reaction to occurat an explosive rate The CHEMLAB at the end of this chapter gives you anopportunity to further investigate the effect of concentration on reaction rates

Surface AreaNow suppose you were to lower a red-hot chunk of steel instead of steelwool into a flask of oxygen gas The oxygen would react with the steel muchmore slowly than it would with the steel wool Using what you know aboutthe collision theory can you explain why You are correct if you said thatfor the same mass of iron steel wool has much more surface area than thechunk of steel The greater surface area of the steel wool allows the oxygenmolecules to collide with many more iron atoms per unit of time

172 Factors Affecting Reaction Rates 537

Figure 17-8

The concentration of oxygenin the air surrounding the steelwool is much less than that ofthe pure oxygen in the flask

The higher oxygen concen-tration accounts for the fasterreaction

Pulverizing (or grinding) a substance is one way to increase its rate ofreaction This is because for the same mass many small particles possessmore total surface area than one large particle So a spoonful of granulatedsugar placed in a cup of water dissolves faster than the same mass of sugarin a single chunk which has less surface area as shown in Figure 17-9 Thisexample illustrates that increasing the surface area of a reactant does notchange its concentration but it does increase the rate of reaction by increas-ing the collision rate between reacting particles

TemperatureGenerally increasing the temperature at which a reaction occurs increasesthe reaction rate For example you know that the reactions that cause foodsto spoil occur much faster at room temperature than when the foods arerefrigerated The graph in Figure 17-10a illustrates that increasing the tem-perature by 10 K can approximately double the rate of a reaction How cana small increase in temperature have such a significant effect

As you learned in Chapter 13 increasing the temperature of a substanceincreases the average kinetic energy of the particles that make up the sub-stance For that reason reacting particles collide more frequently at highertemperatures than at lower temperatures However that fact alone doesnrsquotaccount for the increase in reaction rate with increasing temperature To bet-ter understand how reaction rate varies with temperature examine the graphshown in Figure 17-10b This graph compares the numbers of particles hav-ing sufficient energy to react at temperatures T1 and T2 where T2 is greaterthan T1 The shaded area under each curve represents the number of colli-sions having energy equal to or greater than the activation energy The dot-ted line indicates the activation energy (Ea) for the reaction How do theshaded areas compare The number of high-energy collisions at the highertemperature T2 is much greater than at the lower temperature T1 Thereforeas the temperature increases more collisions result in a reaction

As you can see increasing the temperature of the reactants increases thereaction rate because raising the kinetic energy of the reacting particles rais-es both the collision frequency and the collision energy You can investigatethe relationship between reaction rate and temperature by performing theminiLAB for this chapter

CatalystsYoursquove seen that increasing the temperature andor the concentration of reac-tants can dramatically increase the rate of a reaction However an increasein temperature is not always the best (or most practical) thing to do Forexample suppose that you want to increase the rate of a reaction such as thedecomposition of glucose in a living cell Increasing the temperature andorthe concentration of reactants is not a viable alternative because it mightharm or kill the cell

It is a fact that many chemical reactions in living organisms would notoccur quickly enough to sustain life at normal living temperatures if it werenot for the presence of enzymes An enzyme is a type of catalyst a sub-stance that increases the rate of a chemical reaction without itself being con-sumed in the reaction Although catalysts are important substances in achemical reaction a catalyst does not yield more product and is not includ-ed in the product(s) of the reaction In fact catalysts are not included in thechemical equation

How does a catalyst increase the reaction rate Figure 17-11 on the nextpage shows the energy diagram for an exothermic chemical reaction The redline represents the uncatalyzed reaction pathwaymdashthe reaction pathway withno catalyst present The blue line represents the catalyzed reaction pathway

Compare the amount of time itwould take this train to travelover or around the barrier withthe time it takes to travelthrough the barrier Obviouslytravel is faster through themountain with the aid of thetunnel

Note that the activation energy for the catalyzed reaction is much lower thanfor the uncatalyzed reaction The lower activation energy for the catalyzedreaction means that more collisions have sufficient energy to initiate reac-tion It might help you to visualize this relationship by thinking of the reac-tionrsquos activation energy as a mountain range to be crossed as shown inFigure 17-12 In this analogy the tunnel representing the catalyzed path-way provides an easier and therefore quicker route to the other side of themountains

Another type of substance that affects reaction rates is called an inhibitorUnlike a catalyst which speeds up reaction rates an inhibitor is a substancethat slows down or inhibits reaction rates Some inhibitors in fact actuallyprevent a reaction from happening at all

In our fast-paced world it might seem unlikely that it would be desirableto slow a reaction But if you think about your environment you can proba-bly come up with several uses for inhibitors One of the primary applicationsfor inhibitors is in the food industry where inhibitors are called preserva-tives Figure 17-13 shows how a commercially available fruit freshener

Vocabulary rate lawspecific rate constantreaction ordermethod of initial rates

In Section 171 you learned how to calculate the average rate of a chemicalreaction given the initial and final times and concentrations The word aver-age is important because most chemical reactions slow down as the reactantsare consumed To understand why most reaction rates slow over time recallthat the collision theory states that chemical reactions can occur only whenthe reacting particles collide and that reaction rate depends upon reactantconcentration As reactants are consumed fewer particles collide and thereaction slows Chemists use the concept of rate laws to quantify the resultsof the collision theory in terms of a mathematical relationship between therate of a chemical reaction and the reactant concentration

Reaction Rate LawsThe equation that expresses the mathematical relationship between the rateof a chemical reaction and the concentration of reactants is called a rate lawFor example the reaction A 0 B which is a one-step reaction has only oneactivated complex between reactants and products The rate law for this reac-tion is expressed as

where k is the specific rate constant or a numerical value that relates reac-tion rate and concentration of reactants at a given temperature Units for therate constant include L(mols) L2(mol2s) and sndash1 Depending on the reac-tion conditions especially temperature k is unique for every reaction

The rate law means that the reaction rate is directly proportional to the molarconcentration of A Thus doubling the concentration of A will double the reac-tion rate Increasing the concentration of A by a factor of 5 will increase thereaction rate by a factor of 5 The specific rate constant k does not change withconcentration however k does change with temperature A large value of kmeans that A reacts rapidly to form B What does a small value of k mean

Reaction order In the expression Rate k[A] it is understood that thenotation [A] means the same as [A]1 In other words for reactant A theunderstood exponent 1 is called the reaction order The reaction order for areactant defines how the rate is affected by the concentration of that reactantFor example the rate law for the decomposition of H2O2 is expressed by thefollowing equation

Rate k[H2O2]

Because the reaction rate is directly proportional to the concentration ofH2O2 raised to the first power [H2O2]

1 the decomposition of H2O2 is said tobe first order in H2O2 Because the reaction is first order in H2O2 the reac-tion rate changes in the same proportion that the concentration of H2O2changes So if the H2O2 concentration decreases to one-half its originalvalue the reaction rate is halved as well

Recall from Section 171 that reaction rates are determined from experi-mental data Because reaction order is based on reaction rates it follows thatreaction order also is determined experimentally Finally because the rateconstant describes the reaction rate k too must be determined experimen-tally Figure 17-14 illustrates two of several experimental methods that arecommonly used to measure reaction rates

Other reaction orders The overall reaction order of a chemical reactionis the sum of the orders for the individual reactants in the rate law Manychemical reactions particularly those having more than one reactant are notfirst order Consider the general form for a chemical reaction with two reac-tants In this chemical equation a and b are coefficients

aA bB 0 products

The general rate law for such a reaction is

Rate k[A]m[B]n

where m and n are the reaction orders for A and B respectively Only if thereaction between A and B occurs in a single step (and with a single activat-ed complex) does m a and n b Thatrsquos unlikely however because sin-gle-step reactions are uncommon

For example the reaction between nitrogen monoxide (NO) and hydrogen(H2) is described by the following equation

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

This reaction which occurs in more than one step has the following rate law

Rate k[NO]2[H2]

This rate law was determined experimentally The data tell that the ratedepends on the concentration of the reactants as follows If [NO] doubles therate quadruples if [H2] doubles the rate doubles The reaction is describedas second order in NO first order in H2 and third order overall because thesum of the orders for the individual reactants (the sum of the exponents) is(2 1) or 3

Determining Reaction OrderOne common experimental method of evaluating reaction order is called themethod of initial rates The method of initial rates determines reactionorder by comparing the initial rates of a reaction carried out with varyingreactant concentrations To understand how this method works letrsquos use thegeneral reaction aA bB 0 products Suppose that this reaction is carriedout with varying concentrations of A and B and yields the initial reactionrates shown in Table 17-3

Recall that the general rate law for this type of reaction is

Rate k[A]m[B]n

To determine m the concentrations and reaction rates in Trials 1 and 2 arecompared As you can see from the data while the concentration of Bremains constant the concentration of A in Trial 2 is twice that of Trial 1Note that the initial rate in Trial 2 is twice that of Trial 1 Because doubling[A] doubles the rate the reaction must be first order in A That is because2m 2 m must equal 1 The same method is used to determine n only thistime Trials 2 and 3 are compared Doubling the concentration of B causes therate to increase by four times Because 2n 4 n must equal 2 This infor-mation suggests that the reaction is second order in B giving the followingoverall rate law

Rate k[A]1[B]2

The overall reaction order is third order (sum of exponents 2 1 3)

The average reaction rate you learned to calculate in Section 173 givesimportant information about the reaction over a period of time Howeverchemists also may need to know at what rate the reaction is proceeding at aspecific time A pharmacist developing a new drug treatment might need toknow the progress of a reaction at an exact instant This information makesit possible to adjust the product for maximum performance Can you think ofother situations where it might be critical to know the specific reaction rateat a given time

Instantaneous Reaction RatesThe decomposition of hydrogen peroxide (H2O2) is represented as follows

2H2O2(aq) 0 2H2O(l) O2(g)

For this reaction the decrease in H2O2 concentration over time is shown inFigure 17-15 The curved line shows how the reaction rate decreases as thereaction proceeds The instantaneous rate or the rate of decomposition ata specific time can be determined by finding the slope of the straight linetangent to the curve at that instant This is because the slope of the tangentto the curve at a particular point is [H2O2]t which is one way to expressthe reaction rate In other words the rate of change in H2O2 concentrationrelates to one specific point (or instant) on the graph

Another way to determine the instantaneous rate for a chemical reactionis to use the experimentally determined rate law given the reactant concen-trations and the specific rate constant for the temperature at which the reactionoccurs For example the decomposition of dinitrogen pentoxide (N2O5) intonitrogen dioxide (NO2) and oxygen (O2) is given by the following equation

2NO(g) H2(g) 0 N2O(g) H2O(g)

Calculate the instantaneous rate when the reactant concentrations are[NO] = 000200M and [H2] = 000400M

Reaction MechanismsMost chemical reactions consist of a sequence of two or more simpler reac-tions For example recent evidence indicates that the reaction 2O3 0 3O2occurs in three steps after intense ultraviolet radiation from the sun liberateschlorine atoms from certain compounds in Earthrsquos stratosphere Steps 1 and2 in this reaction may occur simultaneously or in reverse order

1 Chlorine atoms decompose ozone according to the equation Cl O3 0 O2 ClO

2 Ultraviolet radiation causes the decomposition reaction O3 0 O2 O

3 ClO produced in the reaction in step 1 reacts with O produced in step 2according to the equation ClO O 0 Cl O2

Each of the reactions described in steps 1 through 3 is called an elementarystep These three elementary steps comprise the complex reaction 2O3 0 3O2A complex reaction is one that consists of two or more elementary steps Thecomplete sequence of elementary steps that make up a complex reaction iscalled a reaction mechanism Adding the elementary steps in steps 1 through3 and canceling formulas that occur in equal amounts on both sides of the reac-tion arrow produce the net equation for the complex reaction as shown below

Elementary step Cl O3 0 O2 ClO

Elementary step O3 0 O2 O

Elementary step ClO O 0 Cl O2

Complex reaction 2O3 0 3O2

Because chlorine atoms react in step 1 of the reaction mechanism and arere-formed in step 3 chlorine is said to catalyze the decomposition of ozoneDo you know why Because ClO and O are formed in the reactions in steps1 and 2 respectively and are consumed in the reaction in step 3 they arecalled intermediates In a complex reaction an intermediate is a substanceproduced in one elementary step and consumed in a subsequent elementarystep Catalysts and intermediates do not appear in the net chemical equation

Rate-determining step You have probably heard the expression ldquoAchain is no stronger than its weakest linkrdquo Chemical reactions too have aldquoweakest linkrdquo in that a complex reaction can proceed no faster than theslowest of its elementary steps In other words the slowest elementary stepin a reaction mechanism limits the instantaneous rate of the overall reaction

For that reason the slowest of the elementary steps in a complex reaction iscalled the rate-determining step Figure 17-16 illustrates this concept in amanufacturing plant

To see how the rate-determining step affects reaction rate again considerthe gas-phase reaction between hydrogen and nitrogen monoxide discussedearlier in the chapter

2NO 0 N2O2 (fast)

N2O2 H2 0 N2O H2O (slow)

N2O H2 0 N2 H2O (fast)

Although the first and third elementary steps occur relatively fast the mid-dle step is the slowest and it limits the overall reaction rate It is the rate-determining step The relative energy levels of reactants intermediatesproducts and activated complex are illustrated in Figure 17-17

Chemists can make use of instantaneous reaction rates reaction ordersand rate-determining steps to develop efficient ways to manufacture prod-ucts such as pharmaceuticals By knowing which step of the reaction is slow-est a chemist can work to speed up that rate-determining step and therebyincrease the rate of the overall reaction

Section 171 A Model for Reaction Rates

One of the most spectacular chemical reactions the one between liquidhydrogen and liquid oxygen provides the energy to launch rockets intospace as shown on the opposite page This reaction is fast and exothermicYet other reactions and processes yoursquore familiar with such as the hardeningof concrete or the formation of fossil fuels occur at considerably slowerrates The DISCOVERY LAB for this chapter emphasized that the speed atwhich a reaction occurs can vary if other substances are introduced into thereaction In this section yoursquoll learn about a model that scientists use todescribe and calculate the rates at which chemical reactions occur

Expressing Reaction RatesAs you know some chemical reactions are fast and others are slow howev-er fast and slow are inexact relative terms Chemists engineers medicalresearchers and others often need to be more specific

Think about how you express speed or rate in the situations shown inFigure 17-1 on the next page The speed of the sprinter on the track teammay be expressed as meters per second The speed at which the hiker movesmight be expressed differently perhaps as meters per minute We generallydefine the average rate of an action or process to be the change in a givenquantity during a specific period of time Recall from your study of math thatthe Greek letter delta () before a quantity indicates a change in the quanti-ty In equation form average rate or speed is written as

For chemical reactions this equation defines the average rate at whichreactants produce products which is the amount of change of a reactant in agiven period of time Most often chemists are concerned with changes in themolar concentration (molL M) of a reactant or product during a reactionTherefore the reaction rate of a chemical reaction is stated as the change inconcentration of a reactant or product per unit time expressed as mol(Ls)Brackets around the formula for a substance denote the molar concentrationFor example [NO2] represents the molar concentration of NO2

Itrsquos important to understand that reaction rates are determined experimen-tally by measuring the concentrations of reactants andor products in anactual chemical reaction Reaction rates cannot be calculated from balancedequations as stoichiometric amounts can

Suppose you wish to express the average rate of the reaction

CO(g) NO2(g) 0 CO2(g) NO(g)

Do you predict a positive or negative value for this reaction In this case anegative value indicates that the concentration of CO decreases as the reac-tion proceeds

The Collision TheoryYou have learned that reaction rates are calculated from experimental dataBut what are we actually measuring with these calculations Looking atchemical reactions from the molecular level will provide a clearer picture ofexactly what reaction rates measure

Have you ever seen a demolition derby in which the competing vehiclesare constantly colliding Each collision may result in the demolition of one ormore vehicles as shown in Figure 17-2a The reactants in a chemical reactionmust also come together in order to form products as shown in Figure 17-2bThe collision theory states that atoms ions and molecules must collide inorder to react The collision theory summarized in Table 17-2 explains whyreactions occur and how the rates of chemical reactions can be modified

Consider the reaction between hydrogen gas (H2) and oxygen gas (O2)

2H2 O2 0 2H2O

According to the collision theory H2 and O2 molecules must collide in orderto react and produce H2O Now look at the reaction between carbon monox-ide (CO) gas and nitrogen dioxide (NO2) gas at a temperature above 500 K

CO(g) NO2(g) 0 CO2(g) NO(g)

These molecules collide to produce carbon dioxide (CO2) gas and nitrogenmonoxide (NO) gas However detailed calculations of the number of molec-ular collisions per second yield a puzzling resultmdashonly a small fraction ofcollisions produce reactions In this case other factors must be considered

Orientation and the activated complex Why donrsquot the NO2 and COmolecules shown in Figure 17-3a and b react when they collide Analysisof this example indicates that in order for a collision to lead to a reaction thecarbon atom in a CO molecule must contact an oxygen atom in an NO2 mol-ecule at the instant of impact Only in that way can a temporary bondbetween the carbon atom and an oxygen atom form The collisions shown inFigure 17-3a and b do not lead to reactions because the molecules collidewith unfavorable orientations That is because a carbon atom does not con-tact an oxygen atom at the instant of impact the molecules simply rebound

When the orientation of colliding molecules is correct as Figure 17-3cillustrates a reaction occurs as an oxygen atom is transferred from an NO2molecule to a CO molecule A short-lived intermediate substance is formedThe intermediate substance in this case OCONO is called an activated com-plex An activated complex is a temporary unstable arrangement of atomsthat may form products or may break apart to re-form the reactants Becausethe activated complex is as likely to form reactants as it is to form productsit is sometimes referred to as the transition state An activated complex isthe first step leading to the resulting chemical reaction

Activation energy and reaction The collision depicted in Figure 17-3ddoes not lead to a reaction for a different reason Although the CO and NO2molecules collide with a favorable orientation no reaction occurs becausethey collide with insufficient energy to form the activated complex The min-imum amount of energy that reacting particles must have to form the acti-vated complex and lead to a reaction is called the activation energy Ea

Activation energy has a direct influence on the rate of a reaction A highEa means that relatively few collisions will have the required energy to pro-duce the activated complex and the reaction rate will be low On the otherhand a low Ea means that more collisions will have sufficient energy toreact and the reaction rate will be higher The problem-solving LAB belowemphasizes this fact It might be helpful to think of this relationship in termsof a person pushing a heavy cart up a hill If the hill is high a substantialamount of energy and effort will be required to move the cart and it will takea long time to get it to the top If the hill is low less energy will be requiredand the task will be accomplished faster

Figure 17-4 shows the energy diagram for the progress of the reactionbetween carbon monoxide and nitrogen dioxide Does this energy diagramlook somewhat different from those you studied in Chapter 16 Why Inaddition to the energies of the reactants and products this diagram shows theactivation energy of the reaction Activation energy can be thought of as abarrier the reactants must overcome in order to form the products In thiscase the CO and NO2 molecules collide with enough energy to overcome thebarrier and the products formed lie at a lower energy level Do you recall thatreactions that lose energy such as this example are called exothermic reactions

For many reactions the process from reactants to products is reversibleFigure 17-5 shows the reverse endothermic reaction between CO2 and NOto reform CO and NO2 In this reverse reaction the reactants which are themolecules that were formed in the exothermic forward reaction lie at a lowenergy level and must overcome a significant activation energy to reform COand NO2 This requires an input of energy If this reverse reaction isachieved CO and NO2 again lie at a high energy level

The influence of spontaneity Recall from Chapter 16 that reaction spon-taneity is related to change in free energy G If G is negative the reac-tion is spontaneous under the conditions specified If G is positive thereaction is not spontaneous Letrsquos now consider whether spontaneity has anyeffect on reaction rates Are more spontaneous reactions faster than lessspontaneous ones

To investigate the relationship between spontaneity and reaction rate con-sider the following gas-phase reaction between hydrogen and oxygen

2H2(g) O2(g) 0 2H2O(g)

Here G 458 kJ at 298 K (25degC) and 1 atm pressure Because G isnegative the reaction is spontaneous For the same reaction H 484 kJ which means that the reaction is highly exothermic You canexamine the speed of this reaction by filling a tape-wrapped soda bottle withstoichiometric quantities of the two gasesmdashtwo volumes hydrogen and onevolume oxygen A thermometer in the stopper allows you to monitor thetemperature inside the bottle As you watch for evidence of a reaction thetemperature remains constant for hours Have the gases escaped Or havethey simply failed to react If you remove the stopper and hold a burningsplint to the mouth of the bottle a reaction occurs explosively Clearly thehydrogen and oxygen gases have not escaped from the bottle Yet they didnot react noticeably until you supplied additional energy in the form of alighted splint The example shown in Figure 17-6 illustrates this same phe-nomenon The soap bubbles you see billowing from the bowl are filled withhydrogen When the lighted splint introduces additional energy an explo-sive reaction occurs between the hydrogen that was contained in the bub-bles and oxygen in the air

As these examples show reaction spontaneity in the form of G impliesabsolutely nothing about the speed of the reaction G merely indicates thenatural tendency for a reaction or process to proceed Factors other thanspontaneity however do affect the rate of a chemical reaction These factorsare keys in controlling and using the power of chemistry

According to the collision theory chemical reactions occur when moleculescollide in a particular orientation and with sufficient energy to achieve acti-vation energy You can probably identify chemical reactions that occur fastsuch as gasoline combustion and others that occur more slowly such as ironrusting But can the reaction rate of any single reaction vary or is the reac-tion rate constant regardless of the conditions In this section you will learnthat the reaction rate for almost any chemical reaction can be modified byvarying the conditions of the reaction

The Nature of ReactantsAn important factor that affects the rate of a chemical reaction is the reactivenature of the reactants As you know some substances react more readily thanothers For example calcium and sodium are both reactive metals howeverwhat happens when each metal is added to water is distinctly different Whena small piece of calcium is placed in cold water as shown in Figure 17-7athe calcium and water react slowly to form hydrogen gas and aqueous calci-um hydroxide

Ca(s) 2H2O(l) 0 H2(g) Ca(OH)2(aq)

When a small piece of sodium is placed in cold water the sodium and waterreact quickly to form hydrogen gas and aqueous sodium hydroxide as shownin Figure 17-7b

2Na(s) 2H2O(l) 0 H2(g) 2NaOH(aq)

Comparing the two equations itrsquos evident that the reactions are similarHowever the reaction between sodium and water occurs much fasterbecause sodium is more reactive with water than calcium is In fact the reac-tion releases so much heat so quickly that the hydrogen gas ignites as it isformed

ConcentrationReactions speed up when the concentrations of reacting particles areincreased One of the fundamental principles of the collision theory is thatparticles must collide to react The number of particles in a reaction makes adifference in the rate at which the reaction takes place Think about a reac-tion where reactant A combines with reactant B At a given concentration ofA and B the molecules of A collide with B to produce AB at a particular rateWhat happens if the amount of B is increased Increasing the concentrationof B makes more molecules available with which A can collide Reactant Aldquofindsrdquo reactant B more easily because there are more B molecules in thearea which increases probability of collision and ultimately increases therate of reaction between A and B

Look at the two reactions shown in Figure 17-8 Steel wool is first heat-ed over a burner until it is red hot In Figure 17-8a the hot steel wool reactswith oxygen in the air How does this reaction compare with the one inFigure 17-8b in which the hot steel wool is lowered immediately into a flaskcontaining nearly 100 percent oxygenmdashapproximately five times the concen-tration of oxygen in air Applying the collision theory to this reaction thehigher concentration of oxygen increases the collision frequency betweeniron atoms and oxygen molecules which increases the rate of the reaction

If you have ever been near a person using bottled oxygen or seen an oxy-gen generator you may have noticed a sign cautioning against smoking orusing open flames Can you now explain the reason for the caution noticeThe high concentration of oxygen could cause a combustion reaction to occurat an explosive rate The CHEMLAB at the end of this chapter gives you anopportunity to further investigate the effect of concentration on reaction rates

Surface AreaNow suppose you were to lower a red-hot chunk of steel instead of steelwool into a flask of oxygen gas The oxygen would react with the steel muchmore slowly than it would with the steel wool Using what you know aboutthe collision theory can you explain why You are correct if you said thatfor the same mass of iron steel wool has much more surface area than thechunk of steel The greater surface area of the steel wool allows the oxygenmolecules to collide with many more iron atoms per unit of time

172 Factors Affecting Reaction Rates 537

Figure 17-8

The concentration of oxygenin the air surrounding the steelwool is much less than that ofthe pure oxygen in the flask

The higher oxygen concen-tration accounts for the fasterreaction

Pulverizing (or grinding) a substance is one way to increase its rate ofreaction This is because for the same mass many small particles possessmore total surface area than one large particle So a spoonful of granulatedsugar placed in a cup of water dissolves faster than the same mass of sugarin a single chunk which has less surface area as shown in Figure 17-9 Thisexample illustrates that increasing the surface area of a reactant does notchange its concentration but it does increase the rate of reaction by increas-ing the collision rate between reacting particles

TemperatureGenerally increasing the temperature at which a reaction occurs increasesthe reaction rate For example you know that the reactions that cause foodsto spoil occur much faster at room temperature than when the foods arerefrigerated The graph in Figure 17-10a illustrates that increasing the tem-perature by 10 K can approximately double the rate of a reaction How cana small increase in temperature have such a significant effect

As you learned in Chapter 13 increasing the temperature of a substanceincreases the average kinetic energy of the particles that make up the sub-stance For that reason reacting particles collide more frequently at highertemperatures than at lower temperatures However that fact alone doesnrsquotaccount for the increase in reaction rate with increasing temperature To bet-ter understand how reaction rate varies with temperature examine the graphshown in Figure 17-10b This graph compares the numbers of particles hav-ing sufficient energy to react at temperatures T1 and T2 where T2 is greaterthan T1 The shaded area under each curve represents the number of colli-sions having energy equal to or greater than the activation energy The dot-ted line indicates the activation energy (Ea) for the reaction How do theshaded areas compare The number of high-energy collisions at the highertemperature T2 is much greater than at the lower temperature T1 Thereforeas the temperature increases more collisions result in a reaction

As you can see increasing the temperature of the reactants increases thereaction rate because raising the kinetic energy of the reacting particles rais-es both the collision frequency and the collision energy You can investigatethe relationship between reaction rate and temperature by performing theminiLAB for this chapter

CatalystsYoursquove seen that increasing the temperature andor the concentration of reac-tants can dramatically increase the rate of a reaction However an increasein temperature is not always the best (or most practical) thing to do Forexample suppose that you want to increase the rate of a reaction such as thedecomposition of glucose in a living cell Increasing the temperature andorthe concentration of reactants is not a viable alternative because it mightharm or kill the cell

It is a fact that many chemical reactions in living organisms would notoccur quickly enough to sustain life at normal living temperatures if it werenot for the presence of enzymes An enzyme is a type of catalyst a sub-stance that increases the rate of a chemical reaction without itself being con-sumed in the reaction Although catalysts are important substances in achemical reaction a catalyst does not yield more product and is not includ-ed in the product(s) of the reaction In fact catalysts are not included in thechemical equation

Compare the amount of time itwould take this train to travelover or around the barrier withthe time it takes to travelthrough the barrier Obviouslytravel is faster through themountain with the aid of thetunnel

Note that the activation energy for the catalyzed reaction is much lower thanfor the uncatalyzed reaction The lower activation energy for the catalyzedreaction means that more collisions have sufficient energy to initiate reac-tion It might help you to visualize this relationship by thinking of the reac-tionrsquos activation energy as a mountain range to be crossed as shown inFigure 17-12 In this analogy the tunnel representing the catalyzed path-way provides an easier and therefore quicker route to the other side of themountains

Another type of substance that affects reaction rates is called an inhibitorUnlike a catalyst which speeds up reaction rates an inhibitor is a substancethat slows down or inhibits reaction rates Some inhibitors in fact actuallyprevent a reaction from happening at all

In our fast-paced world it might seem unlikely that it would be desirableto slow a reaction But if you think about your environment you can proba-bly come up with several uses for inhibitors One of the primary applicationsfor inhibitors is in the food industry where inhibitors are called preserva-tives Figure 17-13 shows how a commercially available fruit freshener

Heterogeneous and homogeneous catalysts In order to reduce harm-ful engine emissions automobiles manufactured today must have catalyticconverters similar to the one described in How It Works at the end of thechapter The most effective catalysts for this application are transition metaloxides and metals such as palladium and platinum These substances catalyzereactions that convert nitrogen monoxide to nitrogen and oxygen carbonmonoxide to carbon dioxide and unburned gasoline to carbon dioxide andwater Because the catalysts in a catalytic converter are solids and the reac-tions they catalyze are gaseous the catalysts are called heterogeneous cata-lysts A heterogeneous catalyst exists in a physical state different than thatof the reaction it catalyzes A catalyst that exists in the same physical state asthe reaction it catalyzes is called a homogeneous catalyst For example ifboth an enzyme and the reaction it catalyzes are in aqueous solution theenzyme is a homogeneous catalyst

Section 173 Reaction Rate Laws

Objectivesbull Express the relationship

between reaction rate andconcentration

bull Determine reaction ordersusing the method of initialrates

Vocabulary rate lawspecific rate constantreaction ordermethod of initial rates

In Section 171 you learned how to calculate the average rate of a chemicalreaction given the initial and final times and concentrations The word aver-age is important because most chemical reactions slow down as the reactantsare consumed To understand why most reaction rates slow over time recallthat the collision theory states that chemical reactions can occur only whenthe reacting particles collide and that reaction rate depends upon reactantconcentration As reactants are consumed fewer particles collide and thereaction slows Chemists use the concept of rate laws to quantify the resultsof the collision theory in terms of a mathematical relationship between therate of a chemical reaction and the reactant concentration

Reaction Rate LawsThe equation that expresses the mathematical relationship between the rateof a chemical reaction and the concentration of reactants is called a rate lawFor example the reaction A 0 B which is a one-step reaction has only oneactivated complex between reactants and products The rate law for this reac-tion is expressed as

where k is the specific rate constant or a numerical value that relates reac-tion rate and concentration of reactants at a given temperature Units for therate constant include L(mols) L2(mol2s) and sndash1 Depending on the reac-tion conditions especially temperature k is unique for every reaction

The rate law means that the reaction rate is directly proportional to the molarconcentration of A Thus doubling the concentration of A will double the reac-tion rate Increasing the concentration of A by a factor of 5 will increase thereaction rate by a factor of 5 The specific rate constant k does not change withconcentration however k does change with temperature A large value of kmeans that A reacts rapidly to form B What does a small value of k mean

Reaction order In the expression Rate k[A] it is understood that thenotation [A] means the same as [A]1 In other words for reactant A theunderstood exponent 1 is called the reaction order The reaction order for areactant defines how the rate is affected by the concentration of that reactantFor example the rate law for the decomposition of H2O2 is expressed by thefollowing equation

Rate k[H2O2]

Because the reaction rate is directly proportional to the concentration ofH2O2 raised to the first power [H2O2]

1 the decomposition of H2O2 is said tobe first order in H2O2 Because the reaction is first order in H2O2 the reac-tion rate changes in the same proportion that the concentration of H2O2changes So if the H2O2 concentration decreases to one-half its originalvalue the reaction rate is halved as well

Recall from Section 171 that reaction rates are determined from experi-mental data Because reaction order is based on reaction rates it follows thatreaction order also is determined experimentally Finally because the rateconstant describes the reaction rate k too must be determined experimen-tally Figure 17-14 illustrates two of several experimental methods that arecommonly used to measure reaction rates

Other reaction orders The overall reaction order of a chemical reactionis the sum of the orders for the individual reactants in the rate law Manychemical reactions particularly those having more than one reactant are notfirst order Consider the general form for a chemical reaction with two reac-tants In this chemical equation a and b are coefficients

aA bB 0 products

The general rate law for such a reaction is

Rate k[A]m[B]n

where m and n are the reaction orders for A and B respectively Only if thereaction between A and B occurs in a single step (and with a single activat-ed complex) does m a and n b Thatrsquos unlikely however because sin-gle-step reactions are uncommon

For example the reaction between nitrogen monoxide (NO) and hydrogen(H2) is described by the following equation

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

This reaction which occurs in more than one step has the following rate law

Rate k[NO]2[H2]

This rate law was determined experimentally The data tell that the ratedepends on the concentration of the reactants as follows If [NO] doubles therate quadruples if [H2] doubles the rate doubles The reaction is describedas second order in NO first order in H2 and third order overall because thesum of the orders for the individual reactants (the sum of the exponents) is(2 1) or 3

Determining Reaction OrderOne common experimental method of evaluating reaction order is called themethod of initial rates The method of initial rates determines reactionorder by comparing the initial rates of a reaction carried out with varyingreactant concentrations To understand how this method works letrsquos use thegeneral reaction aA bB 0 products Suppose that this reaction is carriedout with varying concentrations of A and B and yields the initial reactionrates shown in Table 17-3

Recall that the general rate law for this type of reaction is

Rate k[A]m[B]n

To determine m the concentrations and reaction rates in Trials 1 and 2 arecompared As you can see from the data while the concentration of Bremains constant the concentration of A in Trial 2 is twice that of Trial 1Note that the initial rate in Trial 2 is twice that of Trial 1 Because doubling[A] doubles the rate the reaction must be first order in A That is because2m 2 m must equal 1 The same method is used to determine n only thistime Trials 2 and 3 are compared Doubling the concentration of B causes therate to increase by four times Because 2n 4 n must equal 2 This infor-mation suggests that the reaction is second order in B giving the followingoverall rate law

Rate k[A]1[B]2

The overall reaction order is third order (sum of exponents 2 1 3)

The average reaction rate you learned to calculate in Section 173 givesimportant information about the reaction over a period of time Howeverchemists also may need to know at what rate the reaction is proceeding at aspecific time A pharmacist developing a new drug treatment might need toknow the progress of a reaction at an exact instant This information makesit possible to adjust the product for maximum performance Can you think ofother situations where it might be critical to know the specific reaction rateat a given time

Instantaneous Reaction RatesThe decomposition of hydrogen peroxide (H2O2) is represented as follows

2H2O2(aq) 0 2H2O(l) O2(g)

For this reaction the decrease in H2O2 concentration over time is shown inFigure 17-15 The curved line shows how the reaction rate decreases as thereaction proceeds The instantaneous rate or the rate of decomposition ata specific time can be determined by finding the slope of the straight linetangent to the curve at that instant This is because the slope of the tangentto the curve at a particular point is [H2O2]t which is one way to expressthe reaction rate In other words the rate of change in H2O2 concentrationrelates to one specific point (or instant) on the graph

Another way to determine the instantaneous rate for a chemical reactionis to use the experimentally determined rate law given the reactant concen-trations and the specific rate constant for the temperature at which the reactionoccurs For example the decomposition of dinitrogen pentoxide (N2O5) intonitrogen dioxide (NO2) and oxygen (O2) is given by the following equation

2 Ultraviolet radiation causes the decomposition reaction O3 0 O2 O

3 ClO produced in the reaction in step 1 reacts with O produced in step 2according to the equation ClO O 0 Cl O2

Each of the reactions described in steps 1 through 3 is called an elementarystep These three elementary steps comprise the complex reaction 2O3 0 3O2A complex reaction is one that consists of two or more elementary steps Thecomplete sequence of elementary steps that make up a complex reaction iscalled a reaction mechanism Adding the elementary steps in steps 1 through3 and canceling formulas that occur in equal amounts on both sides of the reac-tion arrow produce the net equation for the complex reaction as shown below

Elementary step Cl O3 0 O2 ClO

Elementary step ClO O 0 Cl O2

Complex reaction 2O3 0 3O2

Because chlorine atoms react in step 1 of the reaction mechanism and arere-formed in step 3 chlorine is said to catalyze the decomposition of ozoneDo you know why Because ClO and O are formed in the reactions in steps1 and 2 respectively and are consumed in the reaction in step 3 they arecalled intermediates In a complex reaction an intermediate is a substanceproduced in one elementary step and consumed in a subsequent elementarystep Catalysts and intermediates do not appear in the net chemical equation

Rate-determining step You have probably heard the expression ldquoAchain is no stronger than its weakest linkrdquo Chemical reactions too have aldquoweakest linkrdquo in that a complex reaction can proceed no faster than theslowest of its elementary steps In other words the slowest elementary stepin a reaction mechanism limits the instantaneous rate of the overall reaction

For that reason the slowest of the elementary steps in a complex reaction iscalled the rate-determining step Figure 17-16 illustrates this concept in amanufacturing plant

N2O2 H2 0 N2O H2O (slow)

N2O H2 0 N2 H2O (fast)

Although the first and third elementary steps occur relatively fast the mid-dle step is the slowest and it limits the overall reaction rate It is the rate-determining step The relative energy levels of reactants intermediatesproducts and activated complex are illustrated in Figure 17-17

Chemists can make use of instantaneous reaction rates reaction ordersand rate-determining steps to develop efficient ways to manufacture prod-ucts such as pharmaceuticals By knowing which step of the reaction is slow-est a chemist can work to speed up that rate-determining step and therebyincrease the rate of the overall reaction

In many models of catalytic converters this inner structure resembles tubes in a honeycomb arrangement which provides significant surface area to accommodate the catalysts

At high temperatures (300ndash500C) on the platinum catalyst surface the dangerous carbon monoxide and hydrocarbons react with oxygen to form the compounds carbon dioxide and water

Inside the catalytic converter is a porous ceramic structure with a surface coating of platinum and rhodium particles

5 At the rhodium catalyst surface nitric oxide is converted to nitrogen and oxygen

Gasesfrom the engine and the air pass through the exhaust system to the catalytic converter Oxygen intake into the engine at this point is critical for the reactions of the catalysts

Catalytic ConverterConcerns for our environment have made a hugeimpact in the products and processes we use every dayThe catalytic converter is one of those impacts

When a combustion engine converts fuel into ener-gy the reactions of the combustion process are incom-plete Incomplete combustion results in the productionof poisonous carbon monoxide and undesirable nitro-gen oxides Since 1975 catalytic converters havereduced the exhaust emissions that contribute to airpollution by approximately 90

Key Equations and Relationships

Summary171 A Model for Reaction Ratesbull The rate of a chemical reaction is expressed as the

rate at which a reactant is consumed or the rate atwhich a product is formed

bull Reaction rates are generally calculated and expressedin moles per liter per second (mol(Lmiddots))

bull In order to react the particles in a chemical reactionmust collide in a correct orientation and with suffi-cient energy to form the activated complex

bull The rate of a chemical reaction is unrelated to thespontaneity of the reaction

172 Factors Affecting Reaction Ratesbull Key factors that influence the rate of chemical reac-

tions include reactivity concentration surface areatemperature and catalysts

bull Catalysts increase the rates of chemical reactions bylowering activation energies

bull Raising the temperature of a reaction increases therate of the reaction by increasing the collision fre-quency and the number of collisions forming theactivated complex

173 Reaction Rate Lawsbull The mathematical relationship between the rate of a

chemical reaction at a given temperature and theconcentrations of reactants is called the rate law

bull The rate law for a chemical reaction is determinedexperimentally using the method of initial rates

174 Instantaneous Reaction Rates andReaction Mechanisms

bull The instantaneous rate for a chemical reaction iscalculated from the rate law the specific rate con-stant and the concentrations of all reactants

bull Most chemical reactions are complex reactions con-sisting of two or more elementary steps

bull A reaction mechanism is the complete sequence ofelementary steps that make up a complex reaction

bull For a complex reaction the rate-determining steplimits the instantaneous rate of the overall reaction

For chemical reactions this equation defines the average rate at whichreactants produce products which is the amount of change of a reactant in agiven period of time Most often chemists are concerned with changes in themolar concentration (molL M) of a reactant or product during a reactionTherefore the reaction rate of a chemical reaction is stated as the change inconcentration of a reactant or product per unit time expressed as mol(Ls)Brackets around the formula for a substance denote the molar concentrationFor example [NO2] represents the molar concentration of NO2

Itrsquos important to understand that reaction rates are determined experimen-tally by measuring the concentrations of reactants andor products in anactual chemical reaction Reaction rates cannot be calculated from balancedequations as stoichiometric amounts can

Suppose you wish to express the average rate of the reaction

CO(g) NO2(g) 0 CO2(g) NO(g)

during the time period beginning at time t1 and ending at time t2 Calculatingthe rate at which the products of the reaction are produced results in a reac-tion rate having a positive value The rate calculation based on the produc-tion of NO will have the form

For example if the concentration of NO is 000M at time t1 000 s and0010M two seconds after the reaction begins the following calculationgives the average rate of the reaction expressed as moles of NO produced perliter per second

Alternatively you can choose to state the rate of the reaction as the rate atwhich CO is consumed as shown below

Average reaction rate [

Do you predict a positive or negative value for this reaction In this case anegative value indicates that the concentration of CO decreases as the reac-tion proceeds

Actually reaction rates must always be positive When the rate ismeasured by the consumption of a reactant scientists commonly apply anegative sign to the calculation to get a positive reaction rate Therefore thefollowing form of the average rate equation is used to calculate the rate ofconsumption

The Collision TheoryYou have learned that reaction rates are calculated from experimental dataBut what are we actually measuring with these calculations Looking atchemical reactions from the molecular level will provide a clearer picture ofexactly what reaction rates measure

Have you ever seen a demolition derby in which the competing vehiclesare constantly colliding Each collision may result in the demolition of one ormore vehicles as shown in Figure 17-2a The reactants in a chemical reactionmust also come together in order to form products as shown in Figure 17-2bThe collision theory states that atoms ions and molecules must collide inorder to react The collision theory summarized in Table 17-2 explains whyreactions occur and how the rates of chemical reactions can be modified

Consider the reaction between hydrogen gas (H2) and oxygen gas (O2)

2H2 O2 0 2H2O

According to the collision theory H2 and O2 molecules must collide in orderto react and produce H2O Now look at the reaction between carbon monox-ide (CO) gas and nitrogen dioxide (NO2) gas at a temperature above 500 K

CO(g) NO2(g) 0 CO2(g) NO(g)

These molecules collide to produce carbon dioxide (CO2) gas and nitrogenmonoxide (NO) gas However detailed calculations of the number of molec-ular collisions per second yield a puzzling resultmdashonly a small fraction ofcollisions produce reactions In this case other factors must be considered

Orientation and the activated complex Why donrsquot the NO2 and COmolecules shown in Figure 17-3a and b react when they collide Analysisof this example indicates that in order for a collision to lead to a reaction thecarbon atom in a CO molecule must contact an oxygen atom in an NO2 mol-ecule at the instant of impact Only in that way can a temporary bondbetween the carbon atom and an oxygen atom form The collisions shown inFigure 17-3a and b do not lead to reactions because the molecules collidewith unfavorable orientations That is because a carbon atom does not con-tact an oxygen atom at the instant of impact the molecules simply rebound

When the orientation of colliding molecules is correct as Figure 17-3cillustrates a reaction occurs as an oxygen atom is transferred from an NO2molecule to a CO molecule A short-lived intermediate substance is formedThe intermediate substance in this case OCONO is called an activated com-plex An activated complex is a temporary unstable arrangement of atomsthat may form products or may break apart to re-form the reactants Becausethe activated complex is as likely to form reactants as it is to form productsit is sometimes referred to as the transition state An activated complex isthe first step leading to the resulting chemical reaction

Activation energy and reaction The collision depicted in Figure 17-3ddoes not lead to a reaction for a different reason Although the CO and NO2molecules collide with a favorable orientation no reaction occurs becausethey collide with insufficient energy to form the activated complex The min-imum amount of energy that reacting particles must have to form the acti-vated complex and lead to a reaction is called the activation energy Ea

Activation energy has a direct influence on the rate of a reaction A highEa means that relatively few collisions will have the required energy to pro-duce the activated complex and the reaction rate will be low On the otherhand a low Ea means that more collisions will have sufficient energy toreact and the reaction rate will be higher The problem-solving LAB belowemphasizes this fact It might be helpful to think of this relationship in termsof a person pushing a heavy cart up a hill If the hill is high a substantialamount of energy and effort will be required to move the cart and it will takea long time to get it to the top If the hill is low less energy will be requiredand the task will be accomplished faster

Figure 17-4 shows the energy diagram for the progress of the reactionbetween carbon monoxide and nitrogen dioxide Does this energy diagramlook somewhat different from those you studied in Chapter 16 Why Inaddition to the energies of the reactants and products this diagram shows theactivation energy of the reaction Activation energy can be thought of as abarrier the reactants must overcome in order to form the products In thiscase the CO and NO2 molecules collide with enough energy to overcome thebarrier and the products formed lie at a lower energy level Do you recall thatreactions that lose energy such as this example are called exothermic reactions

For many reactions the process from reactants to products is reversibleFigure 17-5 shows the reverse endothermic reaction between CO2 and NOto reform CO and NO2 In this reverse reaction the reactants which are themolecules that were formed in the exothermic forward reaction lie at a lowenergy level and must overcome a significant activation energy to reform COand NO2 This requires an input of energy If this reverse reaction isachieved CO and NO2 again lie at a high energy level

The influence of spontaneity Recall from Chapter 16 that reaction spon-taneity is related to change in free energy G If G is negative the reac-tion is spontaneous under the conditions specified If G is positive thereaction is not spontaneous Letrsquos now consider whether spontaneity has anyeffect on reaction rates Are more spontaneous reactions faster than lessspontaneous ones

To investigate the relationship between spontaneity and reaction rate con-sider the following gas-phase reaction between hydrogen and oxygen

2H2(g) O2(g) 0 2H2O(g)

Here G 458 kJ at 298 K (25degC) and 1 atm pressure Because G isnegative the reaction is spontaneous For the same reaction H 484 kJ which means that the reaction is highly exothermic You canexamine the speed of this reaction by filling a tape-wrapped soda bottle withstoichiometric quantities of the two gasesmdashtwo volumes hydrogen and onevolume oxygen A thermometer in the stopper allows you to monitor thetemperature inside the bottle As you watch for evidence of a reaction thetemperature remains constant for hours Have the gases escaped Or havethey simply failed to react If you remove the stopper and hold a burningsplint to the mouth of the bottle a reaction occurs explosively Clearly thehydrogen and oxygen gases have not escaped from the bottle Yet they didnot react noticeably until you supplied additional energy in the form of alighted splint The example shown in Figure 17-6 illustrates this same phe-nomenon The soap bubbles you see billowing from the bowl are filled withhydrogen When the lighted splint introduces additional energy an explo-sive reaction occurs between the hydrogen that was contained in the bub-bles and oxygen in the air

As these examples show reaction spontaneity in the form of G impliesabsolutely nothing about the speed of the reaction G merely indicates thenatural tendency for a reaction or process to proceed Factors other thanspontaneity however do affect the rate of a chemical reaction These factorsare keys in controlling and using the power of chemistry

Factors Affecting ReactionRates

Objectivesbull Identify factors that affect

the rates of chemical reactions

bull Explain the role of a catalyst

Vocabulary catalystinhibitorheterogeneous catalysthomogeneous catalyst

According to the collision theory chemical reactions occur when moleculescollide in a particular orientation and with sufficient energy to achieve acti-vation energy You can probably identify chemical reactions that occur fastsuch as gasoline combustion and others that occur more slowly such as ironrusting But can the reaction rate of any single reaction vary or is the reac-tion rate constant regardless of the conditions In this section you will learnthat the reaction rate for almost any chemical reaction can be modified byvarying the conditions of the reaction

The Nature of ReactantsAn important factor that affects the rate of a chemical reaction is the reactivenature of the reactants As you know some substances react more readily thanothers For example calcium and sodium are both reactive metals howeverwhat happens when each metal is added to water is distinctly different Whena small piece of calcium is placed in cold water as shown in Figure 17-7athe calcium and water react slowly to form hydrogen gas and aqueous calci-um hydroxide

Ca(s) 2H2O(l) 0 H2(g) Ca(OH)2(aq)

When a small piece of sodium is placed in cold water the sodium and waterreact quickly to form hydrogen gas and aqueous sodium hydroxide as shownin Figure 17-7b

2Na(s) 2H2O(l) 0 H2(g) 2NaOH(aq)

Comparing the two equations itrsquos evident that the reactions are similarHowever the reaction between sodium and water occurs much fasterbecause sodium is more reactive with water than calcium is In fact the reac-tion releases so much heat so quickly that the hydrogen gas ignites as it isformed

ConcentrationReactions speed up when the concentrations of reacting particles areincreased One of the fundamental principles of the collision theory is thatparticles must collide to react The number of particles in a reaction makes adifference in the rate at which the reaction takes place Think about a reac-tion where reactant A combines with reactant B At a given concentration ofA and B the molecules of A collide with B to produce AB at a particular rateWhat happens if the amount of B is increased Increasing the concentrationof B makes more molecules available with which A can collide Reactant Aldquofindsrdquo reactant B more easily because there are more B molecules in thearea which increases probability of collision and ultimately increases therate of reaction between A and B

Look at the two reactions shown in Figure 17-8 Steel wool is first heat-ed over a burner until it is red hot In Figure 17-8a the hot steel wool reactswith oxygen in the air How does this reaction compare with the one inFigure 17-8b in which the hot steel wool is lowered immediately into a flaskcontaining nearly 100 percent oxygenmdashapproximately five times the concen-tration of oxygen in air Applying the collision theory to this reaction thehigher concentration of oxygen increases the collision frequency betweeniron atoms and oxygen molecules which increases the rate of the reaction

If you have ever been near a person using bottled oxygen or seen an oxy-gen generator you may have noticed a sign cautioning against smoking orusing open flames Can you now explain the reason for the caution noticeThe high concentration of oxygen could cause a combustion reaction to occurat an explosive rate The CHEMLAB at the end of this chapter gives you anopportunity to further investigate the effect of concentration on reaction rates

Surface AreaNow suppose you were to lower a red-hot chunk of steel instead of steelwool into a flask of oxygen gas The oxygen would react with the steel muchmore slowly than it would with the steel wool Using what you know aboutthe collision theory can you explain why You are correct if you said thatfor the same mass of iron steel wool has much more surface area than thechunk of steel The greater surface area of the steel wool allows the oxygenmolecules to collide with many more iron atoms per unit of time

Figure 17-8

The concentration of oxygenin the air surrounding the steelwool is much less than that ofthe pure oxygen in the flask

The higher oxygen concen-tration accounts for the fasterreaction

Pulverizing (or grinding) a substance is one way to increase its rate ofreaction This is because for the same mass many small particles possessmore total surface area than one large particle So a spoonful of granulatedsugar placed in a cup of water dissolves faster than the same mass of sugarin a single chunk which has less surface area as shown in Figure 17-9 Thisexample illustrates that increasing the surface area of a reactant does notchange its concentration but it does increase the rate of reaction by increas-ing the collision rate between reacting particles

TemperatureGenerally increasing the temperature at which a reaction occurs increasesthe reaction rate For example you know that the reactions that cause foodsto spoil occur much faster at room temperature than when the foods arerefrigerated The graph in Figure 17-10a illustrates that increasing the tem-perature by 10 K can approximately double the rate of a reaction How cana small increase in temperature have such a significant effect

As you learned in Chapter 13 increasing the temperature of a substanceincreases the average kinetic energy of the particles that make up the sub-stance For that reason reacting particles collide more frequently at highertemperatures than at lower temperatures However that fact alone doesnrsquotaccount for the increase in reaction rate with increasing temperature To bet-ter understand how reaction rate varies with temperature examine the graphshown in Figure 17-10b This graph compares the numbers of particles hav-ing sufficient energy to react at temperatures T1 and T2 where T2 is greaterthan T1 The shaded area under each curve represents the number of colli-sions having energy equal to or greater than the activation energy The dot-ted line indicates the activation energy (Ea) for the reaction How do theshaded areas compare The number of high-energy collisions at the highertemperature T2 is much greater than at the lower temperature T1 Thereforeas the temperature increases more collisions result in a reaction

As you can see increasing the temperature of the reactants increases thereaction rate because raising the kinetic energy of the reacting particles rais-es both the collision frequency and the collision energy You can investigatethe relationship between reaction rate and temperature by performing theminiLAB for this chapter

CatalystsYoursquove seen that increasing the temperature andor the concentration of reac-tants can dramatically increase the rate of a reaction However an increasein temperature is not always the best (or most practical) thing to do Forexample suppose that you want to increase the rate of a reaction such as thedecomposition of glucose in a living cell Increasing the temperature andorthe concentration of reactants is not a viable alternative because it mightharm or kill the cell

It is a fact that many chemical reactions in living organisms would notoccur quickly enough to sustain life at normal living temperatures if it werenot for the presence of enzymes An enzyme is a type of catalyst a sub-stance that increases the rate of a chemical reaction without itself being con-sumed in the reaction Although catalysts are important substances in achemical reaction a catalyst does not yield more product and is not includ-ed in the product(s) of the reaction In fact catalysts are not included in thechemical equation

Compare the amount of time itwould take this train to travelover or around the barrier withthe time it takes to travelthrough the barrier Obviouslytravel is faster through themountain with the aid of thetunnel

Note that the activation energy for the catalyzed reaction is much lower thanfor the uncatalyzed reaction The lower activation energy for the catalyzedreaction means that more collisions have sufficient energy to initiate reac-tion It might help you to visualize this relationship by thinking of the reac-tionrsquos activation energy as a mountain range to be crossed as shown inFigure 17-12 In this analogy the tunnel representing the catalyzed path-way provides an easier and therefore quicker route to the other side of themountains

Another type of substance that affects reaction rates is called an inhibitorUnlike a catalyst which speeds up reaction rates an inhibitor is a substancethat slows down or inhibits reaction rates Some inhibitors in fact actuallyprevent a reaction from happening at all

In our fast-paced world it might seem unlikely that it would be desirableto slow a reaction But if you think about your environment you can proba-bly come up with several uses for inhibitors One of the primary applicationsfor inhibitors is in the food industry where inhibitors are called preserva-tives Figure 17-13 shows how a commercially available fruit freshener

Heterogeneous and homogeneous catalysts In order to reduce harm-ful engine emissions automobiles manufactured today must have catalyticconverters similar to the one described in How It Works at the end of thechapter The most effective catalysts for this application are transition metaloxides and metals such as palladium and platinum These substances catalyzereactions that convert nitrogen monoxide to nitrogen and oxygen carbonmonoxide to carbon dioxide and unburned gasoline to carbon dioxide andwater Because the catalysts in a catalytic converter are solids and the reac-tions they catalyze are gaseous the catalysts are called heterogeneous cata-lysts A heterogeneous catalyst exists in a physical state different than thatof the reaction it catalyzes A catalyst that exists in the same physical state asthe reaction it catalyzes is called a homogeneous catalyst For example ifboth an enzyme and the reaction it catalyzes are in aqueous solution theenzyme is a homogeneous catalyst

Objectivesbull Express the relationship

between reaction rate andconcentration

bull Determine reaction ordersusing the method of initialrates

Vocabulary rate lawspecific rate constantreaction ordermethod of initial rates

In Section 171 you learned how to calculate the average rate of a chemicalreaction given the initial and final times and concentrations The word aver-age is important because most chemical reactions slow down as the reactantsare consumed To understand why most reaction rates slow over time recallthat the collision theory states that chemical reactions can occur only whenthe reacting particles collide and that reaction rate depends upon reactantconcentration As reactants are consumed fewer particles collide and thereaction slows Chemists use the concept of rate laws to quantify the resultsof the collision theory in terms of a mathematical relationship between therate of a chemical reaction and the reactant concentration

Reaction Rate LawsThe equation that expresses the mathematical relationship between the rateof a chemical reaction and the concentration of reactants is called a rate lawFor example the reaction A 0 B which is a one-step reaction has only oneactivated complex between reactants and products The rate law for this reac-tion is expressed as

where k is the specific rate constant or a numerical value that relates reac-tion rate and concentration of reactants at a given temperature Units for therate constant include L(mols) L2(mol2s) and sndash1 Depending on the reac-tion conditions especially temperature k is unique for every reaction

The rate law means that the reaction rate is directly proportional to the molarconcentration of A Thus doubling the concentration of A will double the reac-tion rate Increasing the concentration of A by a factor of 5 will increase thereaction rate by a factor of 5 The specific rate constant k does not change withconcentration however k does change with temperature A large value of kmeans that A reacts rapidly to form B What does a small value of k mean

Reaction order In the expression Rate k[A] it is understood that thenotation [A] means the same as [A]1 In other words for reactant A theunderstood exponent 1 is called the reaction order The reaction order for areactant defines how the rate is affected by the concentration of that reactantFor example the rate law for the decomposition of H2O2 is expressed by thefollowing equation

Rate k[H2O2]

Because the reaction rate is directly proportional to the concentration ofH2O2 raised to the first power [H2O2]

1 the decomposition of H2O2 is said tobe first order in H2O2 Because the reaction is first order in H2O2 the reac-tion rate changes in the same proportion that the concentration of H2O2changes So if the H2O2 concentration decreases to one-half its originalvalue the reaction rate is halved as well

Recall from Section 171 that reaction rates are determined from experi-mental data Because reaction order is based on reaction rates it follows thatreaction order also is determined experimentally Finally because the rateconstant describes the reaction rate k too must be determined experimen-tally Figure 17-14 illustrates two of several experimental methods that arecommonly used to measure reaction rates

Other reaction orders The overall reaction order of a chemical reactionis the sum of the orders for the individual reactants in the rate law Manychemical reactions particularly those having more than one reactant are notfirst order Consider the general form for a chemical reaction with two reac-tants In this chemical equation a and b are coefficients

aA bB 0 products

The general rate law for such a reaction is

Rate k[A]m[B]n

where m and n are the reaction orders for A and B respectively Only if thereaction between A and B occurs in a single step (and with a single activat-ed complex) does m a and n b Thatrsquos unlikely however because sin-gle-step reactions are uncommon

For example the reaction between nitrogen monoxide (NO) and hydrogen(H2) is described by the following equation

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

This reaction which occurs in more than one step has the following rate law

Rate k[NO]2[H2]

This rate law was determined experimentally The data tell that the ratedepends on the concentration of the reactants as follows If [NO] doubles therate quadruples if [H2] doubles the rate doubles The reaction is describedas second order in NO first order in H2 and third order overall because thesum of the orders for the individual reactants (the sum of the exponents) is(2 1) or 3

Determining Reaction OrderOne common experimental method of evaluating reaction order is called themethod of initial rates The method of initial rates determines reactionorder by comparing the initial rates of a reaction carried out with varyingreactant concentrations To understand how this method works letrsquos use thegeneral reaction aA bB 0 products Suppose that this reaction is carriedout with varying concentrations of A and B and yields the initial reactionrates shown in Table 17-3

Recall that the general rate law for this type of reaction is

Rate k[A]m[B]n

To determine m the concentrations and reaction rates in Trials 1 and 2 arecompared As you can see from the data while the concentration of Bremains constant the concentration of A in Trial 2 is twice that of Trial 1Note that the initial rate in Trial 2 is twice that of Trial 1 Because doubling[A] doubles the rate the reaction must be first order in A That is because2m 2 m must equal 1 The same method is used to determine n only thistime Trials 2 and 3 are compared Doubling the concentration of B causes therate to increase by four times Because 2n 4 n must equal 2 This infor-mation suggests that the reaction is second order in B giving the followingoverall rate law

Rate k[A]1[B]2

The overall reaction order is third order (sum of exponents 2 1 3)

The average reaction rate you learned to calculate in Section 173 givesimportant information about the reaction over a period of time Howeverchemists also may need to know at what rate the reaction is proceeding at aspecific time A pharmacist developing a new drug treatment might need toknow the progress of a reaction at an exact instant This information makesit possible to adjust the product for maximum performance Can you think ofother situations where it might be critical to know the specific reaction rateat a given time

Instantaneous Reaction RatesThe decomposition of hydrogen peroxide (H2O2) is represented as follows

2H2O2(aq) 0 2H2O(l) O2(g)

For this reaction the decrease in H2O2 concentration over time is shown inFigure 17-15 The curved line shows how the reaction rate decreases as thereaction proceeds The instantaneous rate or the rate of decomposition ata specific time can be determined by finding the slope of the straight linetangent to the curve at that instant This is because the slope of the tangentto the curve at a particular point is [H2O2]t which is one way to expressthe reaction rate In other words the rate of change in H2O2 concentrationrelates to one specific point (or instant) on the graph

Another way to determine the instantaneous rate for a chemical reactionis to use the experimentally determined rate law given the reactant concen-trations and the specific rate constant for the temperature at which the reactionoccurs For example the decomposition of dinitrogen pentoxide (N2O5) intonitrogen dioxide (NO2) and oxygen (O2) is given by the following equation

2 Ultraviolet radiation causes the decomposition reaction O3 0 O2 O

3 ClO produced in the reaction in step 1 reacts with O produced in step 2according to the equation ClO O 0 Cl O2

Each of the reactions described in steps 1 through 3 is called an elementarystep These three elementary steps comprise the complex reaction 2O3 0 3O2A complex reaction is one that consists of two or more elementary steps Thecomplete sequence of elementary steps that make up a complex reaction iscalled a reaction mechanism Adding the elementary steps in steps 1 through3 and canceling formulas that occur in equal amounts on both sides of the reac-tion arrow produce the net equation for the complex reaction as shown below

Complex reaction 2O3 0 3O2

Because chlorine atoms react in step 1 of the reaction mechanism and arere-formed in step 3 chlorine is said to catalyze the decomposition of ozoneDo you know why Because ClO and O are formed in the reactions in steps1 and 2 respectively and are consumed in the reaction in step 3 they arecalled intermediates In a complex reaction an intermediate is a substanceproduced in one elementary step and consumed in a subsequent elementarystep Catalysts and intermediates do not appear in the net chemical equation

For that reason the slowest of the elementary steps in a complex reaction iscalled the rate-determining step Figure 17-16 illustrates this concept in amanufacturing plant

To see how the rate-determining step affects reaction rate again considerthe gas-phase reaction between hydrogen and nitrogen monoxide discussedearlier in the chapter

N2O2 H2 0 N2O H2O (slow)

N2O H2 0 N2 H2O (fast)

Although the first and third elementary steps occur relatively fast the mid-dle step is the slowest and it limits the overall reaction rate It is the rate-determining step The relative energy levels of reactants intermediatesproducts and activated complex are illustrated in Figure 17-17

Chemists can make use of instantaneous reaction rates reaction ordersand rate-determining steps to develop efficient ways to manufacture prod-ucts such as pharmaceuticals By knowing which step of the reaction is slow-est a chemist can work to speed up that rate-determining step and therebyincrease the rate of the overall reaction

In many models of catalytic converters this inner structure resembles tubes in a honeycomb arrangement which provides significant surface area to accommodate the catalysts

At high temperatures (300ndash500C) on the platinum catalyst surface the dangerous carbon monoxide and hydrocarbons react with oxygen to form the compounds carbon dioxide and water

Inside the catalytic converter is a porous ceramic structure with a surface coating of platinum and rhodium particles

5 At the rhodium catalyst surface nitric oxide is converted to nitrogen and oxygen

Gasesfrom the engine and the air pass through the exhaust system to the catalytic converter Oxygen intake into the engine at this point is critical for the reactions of the catalysts

Catalytic ConverterConcerns for our environment have made a hugeimpact in the products and processes we use every dayThe catalytic converter is one of those impacts

When a combustion engine converts fuel into ener-gy the reactions of the combustion process are incom-plete Incomplete combustion results in the productionof poisonous carbon monoxide and undesirable nitro-gen oxides Since 1975 catalytic converters havereduced the exhaust emissions that contribute to airpollution by approximately 90

Key Equations and Relationships

Summary171 A Model for Reaction Ratesbull The rate of a chemical reaction is expressed as the

rate at which a reactant is consumed or the rate atwhich a product is formed

bull Reaction rates are generally calculated and expressedin moles per liter per second (mol(Lmiddots))

bull In order to react the particles in a chemical reactionmust collide in a correct orientation and with suffi-cient energy to form the activated complex

bull The rate of a chemical reaction is unrelated to thespontaneity of the reaction

172 Factors Affecting Reaction Ratesbull Key factors that influence the rate of chemical reac-

tions include reactivity concentration surface areatemperature and catalysts

bull Catalysts increase the rates of chemical reactions bylowering activation energies

bull Raising the temperature of a reaction increases therate of the reaction by increasing the collision fre-quency and the number of collisions forming theactivated complex

173 Reaction Rate Lawsbull The mathematical relationship between the rate of a

chemical reaction at a given temperature and theconcentrations of reactants is called the rate law

bull The rate law for a chemical reaction is determinedexperimentally using the method of initial rates

174 Instantaneous Reaction Rates andReaction Mechanisms

bull The instantaneous rate for a chemical reaction iscalculated from the rate law the specific rate con-stant and the concentrations of all reactants

bull Most chemical reactions are complex reactions con-sisting of two or more elementary steps

bull A reaction mechanism is the complete sequence ofelementary steps that make up a complex reaction

bull For a complex reaction the rate-determining steplimits the instantaneous rate of the overall reaction

The Collision TheoryYou have learned that reaction rates are calculated from experimental dataBut what are we actually measuring with these calculations Looking atchemical reactions from the molecular level will provide a clearer picture ofexactly what reaction rates measure

Have you ever seen a demolition derby in which the competing vehiclesare constantly colliding Each collision may result in the demolition of one ormore vehicles as shown in Figure 17-2a The reactants in a chemical reactionmust also come together in order to form products as shown in Figure 17-2bThe collision theory states that atoms ions and molecules must collide inorder to react The collision theory summarized in Table 17-2 explains whyreactions occur and how the rates of chemical reactions can be modified

Consider the reaction between hydrogen gas (H2) and oxygen gas (O2)

2H2 O2 0 2H2O

According to the collision theory H2 and O2 molecules must collide in orderto react and produce H2O Now look at the reaction between carbon monox-ide (CO) gas and nitrogen dioxide (NO2) gas at a temperature above 500 K

CO(g) NO2(g) 0 CO2(g) NO(g)

These molecules collide to produce carbon dioxide (CO2) gas and nitrogenmonoxide (NO) gas However detailed calculations of the number of molec-ular collisions per second yield a puzzling resultmdashonly a small fraction ofcollisions produce reactions In this case other factors must be considered

Orientation and the activated complex Why donrsquot the NO2 and COmolecules shown in Figure 17-3a and b react when they collide Analysisof this example indicates that in order for a collision to lead to a reaction thecarbon atom in a CO molecule must contact an oxygen atom in an NO2 mol-ecule at the instant of impact Only in that way can a temporary bondbetween the carbon atom and an oxygen atom form The collisions shown inFigure 17-3a and b do not lead to reactions because the molecules collidewith unfavorable orientations That is because a carbon atom does not con-tact an oxygen atom at the instant of impact the molecules simply rebound

When the orientation of colliding molecules is correct as Figure 17-3cillustrates a reaction occurs as an oxygen atom is transferred from an NO2molecule to a CO molecule A short-lived intermediate substance is formedThe intermediate substance in this case OCONO is called an activated com-plex An activated complex is a temporary unstable arrangement of atomsthat may form products or may break apart to re-form the reactants Becausethe activated complex is as likely to form reactants as it is to form productsit is sometimes referred to as the transition state An activated complex isthe first step leading to the resulting chemical reaction

Activation energy and reaction The collision depicted in Figure 17-3ddoes not lead to a reaction for a different reason Although the CO and NO2molecules collide with a favorable orientation no reaction occurs becausethey collide with insufficient energy to form the activated complex The min-imum amount of energy that reacting particles must have to form the acti-vated complex and lead to a reaction is called the activation energy Ea

Activation energy has a direct influence on the rate of a reaction A highEa means that relatively few collisions will have the required energy to pro-duce the activated complex and the reaction rate will be low On the otherhand a low Ea means that more collisions will have sufficient energy toreact and the reaction rate will be higher The problem-solving LAB belowemphasizes this fact It might be helpful to think of this relationship in termsof a person pushing a heavy cart up a hill If the hill is high a substantialamount of energy and effort will be required to move the cart and it will takea long time to get it to the top If the hill is low less energy will be requiredand the task will be accomplished faster

Speed and Energy of CollisionDesigning an Experiment Controlling therate of a reaction is common in your everydayexperience Consider two of the major appliancesin your kitchen a refrigerator slows down chemi-cal processes that cause food to spoil and anoven speeds up chemical processes that causefoods to cook Petroleum and natural gasesrequire a spark to run your carrsquos engine and heatyour home

AnalysisAccording to collision theory reactants must col-lide with enough energy in order to react Recallfrom the kinetic-molecular theory that mass andvelocity determine the kinetic energy of a parti-

cle In addition temperature is a measure of theaverage kinetic energy of the particles in asample of matter According to kinetic-moleculartheory how are the frequency and energy ofcollisions between gas particles related totemperature

Figure 17-4 shows the energy diagram for the progress of the reactionbetween carbon monoxide and nitrogen dioxide Does this energy diagramlook somewhat different from those you studied in Chapter 16 Why Inaddition to the energies of the reactants and products this diagram shows theactivation energy of the reaction Activation energy can be thought of as abarrier the reactants must overcome in order to form the products In thiscase the CO and NO2 molecules collide with enough energy to overcome thebarrier and the products formed lie at a lower energy level Do you recall thatreactions that lose energy such as this example are called exothermic reactions

For many reactions the process from reactants to products is reversibleFigure 17-5 shows the reverse endothermic reaction between CO2 and NOto reform CO and NO2 In this reverse reaction the reactants which are themolecules that were formed in the exothermic forward reaction lie at a lowenergy level and must overcome a significant activation energy to reform COand NO2 This requires an input of energy If this reverse reaction isachieved CO and NO2 again lie at a high energy level

The influence of spontaneity Recall from Chapter 16 that reaction spon-taneity is related to change in free energy G If G is negative the reac-tion is spontaneous under the conditions specified If G is positive thereaction is not spontaneous Letrsquos now consider whether spontaneity has anyeffect on reaction rates Are more spontaneous reactions faster than lessspontaneous ones

To investigate the relationship between spontaneity and reaction rate con-sider the following gas-phase reaction between hydrogen and oxygen

2H2(g) O2(g) 0 2H2O(g)

Here G 458 kJ at 298 K (25degC) and 1 atm pressure Because G isnegative the reaction is spontaneous For the same reaction H 484 kJ which means that the reaction is highly exothermic You canexamine the speed of this reaction by filling a tape-wrapped soda bottle withstoichiometric quantities of the two gasesmdashtwo volumes hydrogen and onevolume oxygen A thermometer in the stopper allows you to monitor thetemperature inside the bottle As you watch for evidence of a reaction thetemperature remains constant for hours Have the gases escaped Or havethey simply failed to react If you remove the stopper and hold a burningsplint to the mouth of the bottle a reaction occurs explosively Clearly thehydrogen and oxygen gases have not escaped from the bottle Yet they didnot react noticeably until you supplied additional energy in the form of alighted splint The example shown in Figure 17-6 illustrates this same phe-nomenon The soap bubbles you see billowing from the bowl are filled withhydrogen When the lighted splint introduces additional energy an explo-sive reaction occurs between the hydrogen that was contained in the bub-bles and oxygen in the air

According to the collision theory chemical reactions occur when moleculescollide in a particular orientation and with sufficient energy to achieve acti-vation energy You can probably identify chemical reactions that occur fastsuch as gasoline combustion and others that occur more slowly such as ironrusting But can the reaction rate of any single reaction vary or is the reac-tion rate constant regardless of the conditions In this section you will learnthat the reaction rate for almost any chemical reaction can be modified byvarying the conditions of the reaction

The Nature of ReactantsAn important factor that affects the rate of a chemical reaction is the reactivenature of the reactants As you know some substances react more readily thanothers For example calcium and sodium are both reactive metals howeverwhat happens when each metal is added to water is distinctly different Whena small piece of calcium is placed in cold water as shown in Figure 17-7athe calcium and water react slowly to form hydrogen gas and aqueous calci-um hydroxide

Ca(s) 2H2O(l) 0 H2(g) Ca(OH)2(aq)

When a small piece of sodium is placed in cold water the sodium and waterreact quickly to form hydrogen gas and aqueous sodium hydroxide as shownin Figure 17-7b

2Na(s) 2H2O(l) 0 H2(g) 2NaOH(aq)

Comparing the two equations itrsquos evident that the reactions are similarHowever the reaction between sodium and water occurs much fasterbecause sodium is more reactive with water than calcium is In fact the reac-tion releases so much heat so quickly that the hydrogen gas ignites as it isformed

ConcentrationReactions speed up when the concentrations of reacting particles areincreased One of the fundamental principles of the collision theory is thatparticles must collide to react The number of particles in a reaction makes adifference in the rate at which the reaction takes place Think about a reac-tion where reactant A combines with reactant B At a given concentration ofA and B the molecules of A collide with B to produce AB at a particular rateWhat happens if the amount of B is increased Increasing the concentrationof B makes more molecules available with which A can collide Reactant Aldquofindsrdquo reactant B more easily because there are more B molecules in thearea which increases probability of collision and ultimately increases therate of reaction between A and B

Look at the two reactions shown in Figure 17-8 Steel wool is first heat-ed over a burner until it is red hot In Figure 17-8a the hot steel wool reactswith oxygen in the air How does this reaction compare with the one inFigure 17-8b in which the hot steel wool is lowered immediately into a flaskcontaining nearly 100 percent oxygenmdashapproximately five times the concen-tration of oxygen in air Applying the collision theory to this reaction thehigher concentration of oxygen increases the collision frequency betweeniron atoms and oxygen molecules which increases the rate of the reaction

If you have ever been near a person using bottled oxygen or seen an oxy-gen generator you may have noticed a sign cautioning against smoking orusing open flames Can you now explain the reason for the caution noticeThe high concentration of oxygen could cause a combustion reaction to occurat an explosive rate The CHEMLAB at the end of this chapter gives you anopportunity to further investigate the effect of concentration on reaction rates

Surface AreaNow suppose you were to lower a red-hot chunk of steel instead of steelwool into a flask of oxygen gas The oxygen would react with the steel muchmore slowly than it would with the steel wool Using what you know aboutthe collision theory can you explain why You are correct if you said thatfor the same mass of iron steel wool has much more surface area than thechunk of steel The greater surface area of the steel wool allows the oxygenmolecules to collide with many more iron atoms per unit of time

172 Factors Affecting Reaction Rates 537

Figure 17-8

The concentration of oxygenin the air surrounding the steelwool is much less than that ofthe pure oxygen in the flask

The higher oxygen concen-tration accounts for the fasterreaction

Pulverizing (or grinding) a substance is one way to increase its rate ofreaction This is because for the same mass many small particles possessmore total surface area than one large particle So a spoonful of granulatedsugar placed in a cup of water dissolves faster than the same mass of sugarin a single chunk which has less surface area as shown in Figure 17-9 Thisexample illustrates that increasing the surface area of a reactant does notchange its concentration but it does increase the rate of reaction by increas-ing the collision rate between reacting particles

TemperatureGenerally increasing the temperature at which a reaction occurs increasesthe reaction rate For example you know that the reactions that cause foodsto spoil occur much faster at room temperature than when the foods arerefrigerated The graph in Figure 17-10a illustrates that increasing the tem-perature by 10 K can approximately double the rate of a reaction How cana small increase in temperature have such a significant effect

As you learned in Chapter 13 increasing the temperature of a substanceincreases the average kinetic energy of the particles that make up the sub-stance For that reason reacting particles collide more frequently at highertemperatures than at lower temperatures However that fact alone doesnrsquotaccount for the increase in reaction rate with increasing temperature To bet-ter understand how reaction rate varies with temperature examine the graphshown in Figure 17-10b This graph compares the numbers of particles hav-ing sufficient energy to react at temperatures T1 and T2 where T2 is greaterthan T1 The shaded area under each curve represents the number of colli-sions having energy equal to or greater than the activation energy The dot-ted line indicates the activation energy (Ea) for the reaction How do theshaded areas compare The number of high-energy collisions at the highertemperature T2 is much greater than at the lower temperature T1 Thereforeas the temperature increases more collisions result in a reaction

As you can see increasing the temperature of the reactants increases thereaction rate because raising the kinetic energy of the reacting particles rais-es both the collision frequency and the collision energy You can investigatethe relationship between reaction rate and temperature by performing theminiLAB for this chapter

CatalystsYoursquove seen that increasing the temperature andor the concentration of reac-tants can dramatically increase the rate of a reaction However an increasein temperature is not always the best (or most practical) thing to do Forexample suppose that you want to increase the rate of a reaction such as thedecomposition of glucose in a living cell Increasing the temperature andorthe concentration of reactants is not a viable alternative because it mightharm or kill the cell

It is a fact that many chemical reactions in living organisms would notoccur quickly enough to sustain life at normal living temperatures if it werenot for the presence of enzymes An enzyme is a type of catalyst a sub-stance that increases the rate of a chemical reaction without itself being con-sumed in the reaction Although catalysts are important substances in achemical reaction a catalyst does not yield more product and is not includ-ed in the product(s) of the reaction In fact catalysts are not included in thechemical equation

Note that the activation energy for the catalyzed reaction is much lower thanfor the uncatalyzed reaction The lower activation energy for the catalyzedreaction means that more collisions have sufficient energy to initiate reac-tion It might help you to visualize this relationship by thinking of the reac-tionrsquos activation energy as a mountain range to be crossed as shown inFigure 17-12 In this analogy the tunnel representing the catalyzed path-way provides an easier and therefore quicker route to the other side of themountains

Another type of substance that affects reaction rates is called an inhibitorUnlike a catalyst which speeds up reaction rates an inhibitor is a substancethat slows down or inhibits reaction rates Some inhibitors in fact actuallyprevent a reaction from happening at all

In our fast-paced world it might seem unlikely that it would be desirableto slow a reaction But if you think about your environment you can proba-bly come up with several uses for inhibitors One of the primary applicationsfor inhibitors is in the food industry where inhibitors are called preserva-tives Figure 17-13 shows how a commercially available fruit freshener

Heterogeneous and homogeneous catalysts In order to reduce harm-ful engine emissions automobiles manufactured today must have catalyticconverters similar to the one described in How It Works at the end of thechapter The most effective catalysts for this application are transition metaloxides and metals such as palladium and platinum These substances catalyzereactions that convert nitrogen monoxide to nitrogen and oxygen carbonmonoxide to carbon dioxide and unburned gasoline to carbon dioxide andwater Because the catalysts in a catalytic converter are solids and the reac-tions they catalyze are gaseous the catalysts are called heterogeneous cata-lysts A heterogeneous catalyst exists in a physical state different than thatof the reaction it catalyzes A catalyst that exists in the same physical state asthe reaction it catalyzes is called a homogeneous catalyst For example ifboth an enzyme and the reaction it catalyzes are in aqueous solution theenzyme is a homogeneous catalyst

Section 173 Reaction Rate Laws

Objectivesbull Express the relationship

between reaction rate andconcentration

bull Determine reaction ordersusing the method of initialrates

Vocabulary rate lawspecific rate constantreaction ordermethod of initial rates

In Section 171 you learned how to calculate the average rate of a chemicalreaction given the initial and final times and concentrations The word aver-age is important because most chemical reactions slow down as the reactantsare consumed To understand why most reaction rates slow over time recallthat the collision theory states that chemical reactions can occur only whenthe reacting particles collide and that reaction rate depends upon reactantconcentration As reactants are consumed fewer particles collide and thereaction slows Chemists use the concept of rate laws to quantify the resultsof the collision theory in terms of a mathematical relationship between therate of a chemical reaction and the reactant concentration

Reaction Rate LawsThe equation that expresses the mathematical relationship between the rateof a chemical reaction and the concentration of reactants is called a rate lawFor example the reaction A 0 B which is a one-step reaction has only oneactivated complex between reactants and products The rate law for this reac-tion is expressed as

where k is the specific rate constant or a numerical value that relates reac-tion rate and concentration of reactants at a given temperature Units for therate constant include L(mols) L2(mol2s) and sndash1 Depending on the reac-tion conditions especially temperature k is unique for every reaction

The rate law means that the reaction rate is directly proportional to the molarconcentration of A Thus doubling the concentration of A will double the reac-tion rate Increasing the concentration of A by a factor of 5 will increase thereaction rate by a factor of 5 The specific rate constant k does not change withconcentration however k does change with temperature A large value of kmeans that A reacts rapidly to form B What does a small value of k mean

Rate k[A]

Reaction order In the expression Rate k[A] it is understood that thenotation [A] means the same as [A]1 In other words for reactant A theunderstood exponent 1 is called the reaction order The reaction order for areactant defines how the rate is affected by the concentration of that reactantFor example the rate law for the decomposition of H2O2 is expressed by thefollowing equation

Rate k[H2O2]

Because the reaction rate is directly proportional to the concentration ofH2O2 raised to the first power [H2O2]

1 the decomposition of H2O2 is said tobe first order in H2O2 Because the reaction is first order in H2O2 the reac-tion rate changes in the same proportion that the concentration of H2O2changes So if the H2O2 concentration decreases to one-half its originalvalue the reaction rate is halved as well

Recall from Section 171 that reaction rates are determined from experi-mental data Because reaction order is based on reaction rates it follows thatreaction order also is determined experimentally Finally because the rateconstant describes the reaction rate k too must be determined experimen-tally Figure 17-14 illustrates two of several experimental methods that arecommonly used to measure reaction rates

Other reaction orders The overall reaction order of a chemical reactionis the sum of the orders for the individual reactants in the rate law Manychemical reactions particularly those having more than one reactant are notfirst order Consider the general form for a chemical reaction with two reac-tants In this chemical equation a and b are coefficients

aA bB 0 products

The general rate law for such a reaction is

Rate k[A]m[B]n

where m and n are the reaction orders for A and B respectively Only if thereaction between A and B occurs in a single step (and with a single activat-ed complex) does m a and n b Thatrsquos unlikely however because sin-gle-step reactions are uncommon

For example the reaction between nitrogen monoxide (NO) and hydrogen(H2) is described by the following equation

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

This reaction which occurs in more than one step has the following rate law

Rate k[NO]2[H2]

This rate law was determined experimentally The data tell that the ratedepends on the concentration of the reactants as follows If [NO] doubles therate quadruples if [H2] doubles the rate doubles The reaction is describedas second order in NO first order in H2 and third order overall because thesum of the orders for the individual reactants (the sum of the exponents) is(2 1) or 3

Determining Reaction OrderOne common experimental method of evaluating reaction order is called themethod of initial rates The method of initial rates determines reactionorder by comparing the initial rates of a reaction carried out with varyingreactant concentrations To understand how this method works letrsquos use thegeneral reaction aA bB 0 products Suppose that this reaction is carriedout with varying concentrations of A and B and yields the initial reactionrates shown in Table 17-3

Recall that the general rate law for this type of reaction is

Rate k[A]m[B]n

To determine m the concentrations and reaction rates in Trials 1 and 2 arecompared As you can see from the data while the concentration of Bremains constant the concentration of A in Trial 2 is twice that of Trial 1Note that the initial rate in Trial 2 is twice that of Trial 1 Because doubling[A] doubles the rate the reaction must be first order in A That is because2m 2 m must equal 1 The same method is used to determine n only thistime Trials 2 and 3 are compared Doubling the concentration of B causes therate to increase by four times Because 2n 4 n must equal 2 This infor-mation suggests that the reaction is second order in B giving the followingoverall rate law

Rate k[A]1[B]2

The overall reaction order is third order (sum of exponents 2 1 3)

The average reaction rate you learned to calculate in Section 173 givesimportant information about the reaction over a period of time Howeverchemists also may need to know at what rate the reaction is proceeding at aspecific time A pharmacist developing a new drug treatment might need toknow the progress of a reaction at an exact instant This information makesit possible to adjust the product for maximum performance Can you think ofother situations where it might be critical to know the specific reaction rateat a given time

Instantaneous Reaction RatesThe decomposition of hydrogen peroxide (H2O2) is represented as follows

2H2O2(aq) 0 2H2O(l) O2(g)

For this reaction the decrease in H2O2 concentration over time is shown inFigure 17-15 The curved line shows how the reaction rate decreases as thereaction proceeds The instantaneous rate or the rate of decomposition ata specific time can be determined by finding the slope of the straight linetangent to the curve at that instant This is because the slope of the tangentto the curve at a particular point is [H2O2]t which is one way to expressthe reaction rate In other words the rate of change in H2O2 concentrationrelates to one specific point (or instant) on the graph

Another way to determine the instantaneous rate for a chemical reactionis to use the experimentally determined rate law given the reactant concen-trations and the specific rate constant for the temperature at which the reactionoccurs For example the decomposition of dinitrogen pentoxide (N2O5) intonitrogen dioxide (NO2) and oxygen (O2) is given by the following equation

Because chlorine atoms react in step 1 of the reaction mechanism and arere-formed in step 3 chlorine is said to catalyze the decomposition of ozoneDo you know why Because ClO and O are formed in the reactions in steps1 and 2 respectively and are consumed in the reaction in step 3 they arecalled intermediates In a complex reaction an intermediate is a substanceproduced in one elementary step and consumed in a subsequent elementarystep Catalysts and intermediates do not appear in the net chemical equation

Rate-determining step You have probably heard the expression ldquoAchain is no stronger than its weakest linkrdquo Chemical reactions too have aldquoweakest linkrdquo in that a complex reaction can proceed no faster than theslowest of its elementary steps In other words the slowest elementary stepin a reaction mechanism limits the instantaneous rate of the overall reaction

For that reason the slowest of the elementary steps in a complex reaction iscalled the rate-determining step Figure 17-16 illustrates this concept in amanufacturing plant

To see how the rate-determining step affects reaction rate again considerthe gas-phase reaction between hydrogen and nitrogen monoxide discussedearlier in the chapter

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

A proposed mechanism for this reaction consists of the following elementarysteps

2NO 0 N2O2 (fast)

N2O2 H2 0 N2O H2O (slow)

N2O H2 0 N2 H2O (fast)

Although the first and third elementary steps occur relatively fast the mid-dle step is the slowest and it limits the overall reaction rate It is the rate-determining step The relative energy levels of reactants intermediatesproducts and activated complex are illustrated in Figure 17-17

Chemists can make use of instantaneous reaction rates reaction ordersand rate-determining steps to develop efficient ways to manufacture prod-ucts such as pharmaceuticals By knowing which step of the reaction is slow-est a chemist can work to speed up that rate-determining step and therebyincrease the rate of the overall reaction

In many models of catalytic converters this inner structure resembles tubes in a honeycomb arrangement which provides significant surface area to accommodate the catalysts

At high temperatures (300ndash500C) on the platinum catalyst surface the dangerous carbon monoxide and hydrocarbons react with oxygen to form the compounds carbon dioxide and water

Inside the catalytic converter is a porous ceramic structure with a surface coating of platinum and rhodium particles

Gasesfrom the engine and the air pass through the exhaust system to the catalytic converter Oxygen intake into the engine at this point is critical for the reactions of the catalysts

Catalytic ConverterConcerns for our environment have made a hugeimpact in the products and processes we use every dayThe catalytic converter is one of those impacts

When a combustion engine converts fuel into ener-gy the reactions of the combustion process are incom-plete Incomplete combustion results in the productionof poisonous carbon monoxide and undesirable nitro-gen oxides Since 1975 catalytic converters havereduced the exhaust emissions that contribute to airpollution by approximately 90

The Collision TheoryYou have learned that reaction rates are calculated from experimental dataBut what are we actually measuring with these calculations Looking atchemical reactions from the molecular level will provide a clearer picture ofexactly what reaction rates measure

Have you ever seen a demolition derby in which the competing vehiclesare constantly colliding Each collision may result in the demolition of one ormore vehicles as shown in Figure 17-2a The reactants in a chemical reactionmust also come together in order to form products as shown in Figure 17-2bThe collision theory states that atoms ions and molecules must collide inorder to react The collision theory summarized in Table 17-2 explains whyreactions occur and how the rates of chemical reactions can be modified

Consider the reaction between hydrogen gas (H2) and oxygen gas (O2)

2H2 O2 0 2H2O

According to the collision theory H2 and O2 molecules must collide in orderto react and produce H2O Now look at the reaction between carbon monox-ide (CO) gas and nitrogen dioxide (NO2) gas at a temperature above 500 K

CO(g) NO2(g) 0 CO2(g) NO(g)

These molecules collide to produce carbon dioxide (CO2) gas and nitrogenmonoxide (NO) gas However detailed calculations of the number of molec-ular collisions per second yield a puzzling resultmdashonly a small fraction ofcollisions produce reactions In this case other factors must be considered

Orientation and the activated complex Why donrsquot the NO2 and COmolecules shown in Figure 17-3a and b react when they collide Analysisof this example indicates that in order for a collision to lead to a reaction thecarbon atom in a CO molecule must contact an oxygen atom in an NO2 mol-ecule at the instant of impact Only in that way can a temporary bondbetween the carbon atom and an oxygen atom form The collisions shown inFigure 17-3a and b do not lead to reactions because the molecules collidewith unfavorable orientations That is because a carbon atom does not con-tact an oxygen atom at the instant of impact the molecules simply rebound

When the orientation of colliding molecules is correct as Figure 17-3cillustrates a reaction occurs as an oxygen atom is transferred from an NO2molecule to a CO molecule A short-lived intermediate substance is formedThe intermediate substance in this case OCONO is called an activated com-plex An activated complex is a temporary unstable arrangement of atomsthat may form products or may break apart to re-form the reactants Becausethe activated complex is as likely to form reactants as it is to form productsit is sometimes referred to as the transition state An activated complex isthe first step leading to the resulting chemical reaction

Activation energy and reaction The collision depicted in Figure 17-3ddoes not lead to a reaction for a different reason Although the CO and NO2molecules collide with a favorable orientation no reaction occurs becausethey collide with insufficient energy to form the activated complex The min-imum amount of energy that reacting particles must have to form the acti-vated complex and lead to a reaction is called the activation energy Ea

Activation energy has a direct influence on the rate of a reaction A highEa means that relatively few collisions will have the required energy to pro-duce the activated complex and the reaction rate will be low On the otherhand a low Ea means that more collisions will have sufficient energy toreact and the reaction rate will be higher The problem-solving LAB belowemphasizes this fact It might be helpful to think of this relationship in termsof a person pushing a heavy cart up a hill If the hill is high a substantialamount of energy and effort will be required to move the cart and it will takea long time to get it to the top If the hill is low less energy will be requiredand the task will be accomplished faster

Figure 17-4 shows the energy diagram for the progress of the reactionbetween carbon monoxide and nitrogen dioxide Does this energy diagramlook somewhat different from those you studied in Chapter 16 Why Inaddition to the energies of the reactants and products this diagram shows theactivation energy of the reaction Activation energy can be thought of as abarrier the reactants must overcome in order to form the products In thiscase the CO and NO2 molecules collide with enough energy to overcome thebarrier and the products formed lie at a lower energy level Do you recall thatreactions that lose energy such as this example are called exothermic reactions

For many reactions the process from reactants to products is reversibleFigure 17-5 shows the reverse endothermic reaction between CO2 and NOto reform CO and NO2 In this reverse reaction the reactants which are themolecules that were formed in the exothermic forward reaction lie at a lowenergy level and must overcome a significant activation energy to reform COand NO2 This requires an input of energy If this reverse reaction isachieved CO and NO2 again lie at a high energy level

The influence of spontaneity Recall from Chapter 16 that reaction spon-taneity is related to change in free energy G If G is negative the reac-tion is spontaneous under the conditions specified If G is positive thereaction is not spontaneous Letrsquos now consider whether spontaneity has anyeffect on reaction rates Are more spontaneous reactions faster than lessspontaneous ones

To investigate the relationship between spontaneity and reaction rate con-sider the following gas-phase reaction between hydrogen and oxygen

2H2(g) O2(g) 0 2H2O(g)

Here G 458 kJ at 298 K (25degC) and 1 atm pressure Because G isnegative the reaction is spontaneous For the same reaction H 484 kJ which means that the reaction is highly exothermic You canexamine the speed of this reaction by filling a tape-wrapped soda bottle withstoichiometric quantities of the two gasesmdashtwo volumes hydrogen and onevolume oxygen A thermometer in the stopper allows you to monitor thetemperature inside the bottle As you watch for evidence of a reaction thetemperature remains constant for hours Have the gases escaped Or havethey simply failed to react If you remove the stopper and hold a burningsplint to the mouth of the bottle a reaction occurs explosively Clearly thehydrogen and oxygen gases have not escaped from the bottle Yet they didnot react noticeably until you supplied additional energy in the form of alighted splint The example shown in Figure 17-6 illustrates this same phe-nomenon The soap bubbles you see billowing from the bowl are filled withhydrogen When the lighted splint introduces additional energy an explo-sive reaction occurs between the hydrogen that was contained in the bub-bles and oxygen in the air

As these examples show reaction spontaneity in the form of G impliesabsolutely nothing about the speed of the reaction G merely indicates thenatural tendency for a reaction or process to proceed Factors other thanspontaneity however do affect the rate of a chemical reaction These factorsare keys in controlling and using the power of chemistry

Factors Affecting ReactionRates

Vocabulary catalystinhibitorheterogeneous catalysthomogeneous catalyst

According to the collision theory chemical reactions occur when moleculescollide in a particular orientation and with sufficient energy to achieve acti-vation energy You can probably identify chemical reactions that occur fastsuch as gasoline combustion and others that occur more slowly such as ironrusting But can the reaction rate of any single reaction vary or is the reac-tion rate constant regardless of the conditions In this section you will learnthat the reaction rate for almost any chemical reaction can be modified byvarying the conditions of the reaction

The Nature of ReactantsAn important factor that affects the rate of a chemical reaction is the reactivenature of the reactants As you know some substances react more readily thanothers For example calcium and sodium are both reactive metals howeverwhat happens when each metal is added to water is distinctly different Whena small piece of calcium is placed in cold water as shown in Figure 17-7athe calcium and water react slowly to form hydrogen gas and aqueous calci-um hydroxide

ConcentrationReactions speed up when the concentrations of reacting particles areincreased One of the fundamental principles of the collision theory is thatparticles must collide to react The number of particles in a reaction makes adifference in the rate at which the reaction takes place Think about a reac-tion where reactant A combines with reactant B At a given concentration ofA and B the molecules of A collide with B to produce AB at a particular rateWhat happens if the amount of B is increased Increasing the concentrationof B makes more molecules available with which A can collide Reactant Aldquofindsrdquo reactant B more easily because there are more B molecules in thearea which increases probability of collision and ultimately increases therate of reaction between A and B

Look at the two reactions shown in Figure 17-8 Steel wool is first heat-ed over a burner until it is red hot In Figure 17-8a the hot steel wool reactswith oxygen in the air How does this reaction compare with the one inFigure 17-8b in which the hot steel wool is lowered immediately into a flaskcontaining nearly 100 percent oxygenmdashapproximately five times the concen-tration of oxygen in air Applying the collision theory to this reaction thehigher concentration of oxygen increases the collision frequency betweeniron atoms and oxygen molecules which increases the rate of the reaction

If you have ever been near a person using bottled oxygen or seen an oxy-gen generator you may have noticed a sign cautioning against smoking orusing open flames Can you now explain the reason for the caution noticeThe high concentration of oxygen could cause a combustion reaction to occurat an explosive rate The CHEMLAB at the end of this chapter gives you anopportunity to further investigate the effect of concentration on reaction rates

Surface AreaNow suppose you were to lower a red-hot chunk of steel instead of steelwool into a flask of oxygen gas The oxygen would react with the steel muchmore slowly than it would with the steel wool Using what you know aboutthe collision theory can you explain why You are correct if you said thatfor the same mass of iron steel wool has much more surface area than thechunk of steel The greater surface area of the steel wool allows the oxygenmolecules to collide with many more iron atoms per unit of time

Figure 17-8

The concentration of oxygenin the air surrounding the steelwool is much less than that ofthe pure oxygen in the flask

The higher oxygen concen-tration accounts for the fasterreaction

Pulverizing (or grinding) a substance is one way to increase its rate ofreaction This is because for the same mass many small particles possessmore total surface area than one large particle So a spoonful of granulatedsugar placed in a cup of water dissolves faster than the same mass of sugarin a single chunk which has less surface area as shown in Figure 17-9 Thisexample illustrates that increasing the surface area of a reactant does notchange its concentration but it does increase the rate of reaction by increas-ing the collision rate between reacting particles

TemperatureGenerally increasing the temperature at which a reaction occurs increasesthe reaction rate For example you know that the reactions that cause foodsto spoil occur much faster at room temperature than when the foods arerefrigerated The graph in Figure 17-10a illustrates that increasing the tem-perature by 10 K can approximately double the rate of a reaction How cana small increase in temperature have such a significant effect

As you learned in Chapter 13 increasing the temperature of a substanceincreases the average kinetic energy of the particles that make up the sub-stance For that reason reacting particles collide more frequently at highertemperatures than at lower temperatures However that fact alone doesnrsquotaccount for the increase in reaction rate with increasing temperature To bet-ter understand how reaction rate varies with temperature examine the graphshown in Figure 17-10b This graph compares the numbers of particles hav-ing sufficient energy to react at temperatures T1 and T2 where T2 is greaterthan T1 The shaded area under each curve represents the number of colli-sions having energy equal to or greater than the activation energy The dot-ted line indicates the activation energy (Ea) for the reaction How do theshaded areas compare The number of high-energy collisions at the highertemperature T2 is much greater than at the lower temperature T1 Thereforeas the temperature increases more collisions result in a reaction

As you can see increasing the temperature of the reactants increases thereaction rate because raising the kinetic energy of the reacting particles rais-es both the collision frequency and the collision energy You can investigatethe relationship between reaction rate and temperature by performing theminiLAB for this chapter

CatalystsYoursquove seen that increasing the temperature andor the concentration of reac-tants can dramatically increase the rate of a reaction However an increasein temperature is not always the best (or most practical) thing to do Forexample suppose that you want to increase the rate of a reaction such as thedecomposition of glucose in a living cell Increasing the temperature andorthe concentration of reactants is not a viable alternative because it mightharm or kill the cell

It is a fact that many chemical reactions in living organisms would notoccur quickly enough to sustain life at normal living temperatures if it werenot for the presence of enzymes An enzyme is a type of catalyst a sub-stance that increases the rate of a chemical reaction without itself being con-sumed in the reaction Although catalysts are important substances in achemical reaction a catalyst does not yield more product and is not includ-ed in the product(s) of the reaction In fact catalysts are not included in thechemical equation

Note that the activation energy for the catalyzed reaction is much lower thanfor the uncatalyzed reaction The lower activation energy for the catalyzedreaction means that more collisions have sufficient energy to initiate reac-tion It might help you to visualize this relationship by thinking of the reac-tionrsquos activation energy as a mountain range to be crossed as shown inFigure 17-12 In this analogy the tunnel representing the catalyzed path-way provides an easier and therefore quicker route to the other side of themountains

Another type of substance that affects reaction rates is called an inhibitorUnlike a catalyst which speeds up reaction rates an inhibitor is a substancethat slows down or inhibits reaction rates Some inhibitors in fact actuallyprevent a reaction from happening at all

In our fast-paced world it might seem unlikely that it would be desirableto slow a reaction But if you think about your environment you can proba-bly come up with several uses for inhibitors One of the primary applicationsfor inhibitors is in the food industry where inhibitors are called preserva-tives Figure 17-13 shows how a commercially available fruit freshener

Heterogeneous and homogeneous catalysts In order to reduce harm-ful engine emissions automobiles manufactured today must have catalyticconverters similar to the one described in How It Works at the end of thechapter The most effective catalysts for this application are transition metaloxides and metals such as palladium and platinum These substances catalyzereactions that convert nitrogen monoxide to nitrogen and oxygen carbonmonoxide to carbon dioxide and unburned gasoline to carbon dioxide andwater Because the catalysts in a catalytic converter are solids and the reac-tions they catalyze are gaseous the catalysts are called heterogeneous cata-lysts A heterogeneous catalyst exists in a physical state different than thatof the reaction it catalyzes A catalyst that exists in the same physical state asthe reaction it catalyzes is called a homogeneous catalyst For example ifboth an enzyme and the reaction it catalyzes are in aqueous solution theenzyme is a homogeneous catalyst

Objectivesbull Express the relationship

between reaction rate andconcentration

bull Determine reaction ordersusing the method of initialrates

Vocabulary rate lawspecific rate constantreaction ordermethod of initial rates

In Section 171 you learned how to calculate the average rate of a chemicalreaction given the initial and final times and concentrations The word aver-age is important because most chemical reactions slow down as the reactantsare consumed To understand why most reaction rates slow over time recallthat the collision theory states that chemical reactions can occur only whenthe reacting particles collide and that reaction rate depends upon reactantconcentration As reactants are consumed fewer particles collide and thereaction slows Chemists use the concept of rate laws to quantify the resultsof the collision theory in terms of a mathematical relationship between therate of a chemical reaction and the reactant concentration

Reaction Rate LawsThe equation that expresses the mathematical relationship between the rateof a chemical reaction and the concentration of reactants is called a rate lawFor example the reaction A 0 B which is a one-step reaction has only oneactivated complex between reactants and products The rate law for this reac-tion is expressed as

where k is the specific rate constant or a numerical value that relates reac-tion rate and concentration of reactants at a given temperature Units for therate constant include L(mols) L2(mol2s) and sndash1 Depending on the reac-tion conditions especially temperature k is unique for every reaction

The rate law means that the reaction rate is directly proportional to the molarconcentration of A Thus doubling the concentration of A will double the reac-tion rate Increasing the concentration of A by a factor of 5 will increase thereaction rate by a factor of 5 The specific rate constant k does not change withconcentration however k does change with temperature A large value of kmeans that A reacts rapidly to form B What does a small value of k mean

Reaction order In the expression Rate k[A] it is understood that thenotation [A] means the same as [A]1 In other words for reactant A theunderstood exponent 1 is called the reaction order The reaction order for areactant defines how the rate is affected by the concentration of that reactantFor example the rate law for the decomposition of H2O2 is expressed by thefollowing equation

Rate k[H2O2]

Because the reaction rate is directly proportional to the concentration ofH2O2 raised to the first power [H2O2]

1 the decomposition of H2O2 is said tobe first order in H2O2 Because the reaction is first order in H2O2 the reac-tion rate changes in the same proportion that the concentration of H2O2changes So if the H2O2 concentration decreases to one-half its originalvalue the reaction rate is halved as well

Recall from Section 171 that reaction rates are determined from experi-mental data Because reaction order is based on reaction rates it follows thatreaction order also is determined experimentally Finally because the rateconstant describes the reaction rate k too must be determined experimen-tally Figure 17-14 illustrates two of several experimental methods that arecommonly used to measure reaction rates

Other reaction orders The overall reaction order of a chemical reactionis the sum of the orders for the individual reactants in the rate law Manychemical reactions particularly those having more than one reactant are notfirst order Consider the general form for a chemical reaction with two reac-tants In this chemical equation a and b are coefficients

aA bB 0 products

The general rate law for such a reaction is

Rate k[A]m[B]n

where m and n are the reaction orders for A and B respectively Only if thereaction between A and B occurs in a single step (and with a single activat-ed complex) does m a and n b Thatrsquos unlikely however because sin-gle-step reactions are uncommon

For example the reaction between nitrogen monoxide (NO) and hydrogen(H2) is described by the following equation

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

This reaction which occurs in more than one step has the following rate law

Rate k[NO]2[H2]

This rate law was determined experimentally The data tell that the ratedepends on the concentration of the reactants as follows If [NO] doubles therate quadruples if [H2] doubles the rate doubles The reaction is describedas second order in NO first order in H2 and third order overall because thesum of the orders for the individual reactants (the sum of the exponents) is(2 1) or 3

Determining Reaction OrderOne common experimental method of evaluating reaction order is called themethod of initial rates The method of initial rates determines reactionorder by comparing the initial rates of a reaction carried out with varyingreactant concentrations To understand how this method works letrsquos use thegeneral reaction aA bB 0 products Suppose that this reaction is carriedout with varying concentrations of A and B and yields the initial reactionrates shown in Table 17-3

Recall that the general rate law for this type of reaction is

Rate k[A]m[B]n

To determine m the concentrations and reaction rates in Trials 1 and 2 arecompared As you can see from the data while the concentration of Bremains constant the concentration of A in Trial 2 is twice that of Trial 1Note that the initial rate in Trial 2 is twice that of Trial 1 Because doubling[A] doubles the rate the reaction must be first order in A That is because2m 2 m must equal 1 The same method is used to determine n only thistime Trials 2 and 3 are compared Doubling the concentration of B causes therate to increase by four times Because 2n 4 n must equal 2 This infor-mation suggests that the reaction is second order in B giving the followingoverall rate law

Rate k[A]1[B]2

The overall reaction order is third order (sum of exponents 2 1 3)

The average reaction rate you learned to calculate in Section 173 givesimportant information about the reaction over a period of time Howeverchemists also may need to know at what rate the reaction is proceeding at aspecific time A pharmacist developing a new drug treatment might need toknow the progress of a reaction at an exact instant This information makesit possible to adjust the product for maximum performance Can you think ofother situations where it might be critical to know the specific reaction rateat a given time

Instantaneous Reaction RatesThe decomposition of hydrogen peroxide (H2O2) is represented as follows

2H2O2(aq) 0 2H2O(l) O2(g)

For this reaction the decrease in H2O2 concentration over time is shown inFigure 17-15 The curved line shows how the reaction rate decreases as thereaction proceeds The instantaneous rate or the rate of decomposition ata specific time can be determined by finding the slope of the straight linetangent to the curve at that instant This is because the slope of the tangentto the curve at a particular point is [H2O2]t which is one way to expressthe reaction rate In other words the rate of change in H2O2 concentrationrelates to one specific point (or instant) on the graph

Another way to determine the instantaneous rate for a chemical reactionis to use the experimentally determined rate law given the reactant concen-trations and the specific rate constant for the temperature at which the reactionoccurs For example the decomposition of dinitrogen pentoxide (N2O5) intonitrogen dioxide (NO2) and oxygen (O2) is given by the following equation

2 Ultraviolet radiation causes the decomposition reaction O3 0 O2 O

3 ClO produced in the reaction in step 1 reacts with O produced in step 2according to the equation ClO O 0 Cl O2

Each of the reactions described in steps 1 through 3 is called an elementarystep These three elementary steps comprise the complex reaction 2O3 0 3O2A complex reaction is one that consists of two or more elementary steps Thecomplete sequence of elementary steps that make up a complex reaction iscalled a reaction mechanism Adding the elementary steps in steps 1 through3 and canceling formulas that occur in equal amounts on both sides of the reac-tion arrow produce the net equation for the complex reaction as shown below

Elementary step ClO O 0 Cl O2

Complex reaction 2O3 0 3O2

Because chlorine atoms react in step 1 of the reaction mechanism and arere-formed in step 3 chlorine is said to catalyze the decomposition of ozoneDo you know why Because ClO and O are formed in the reactions in steps1 and 2 respectively and are consumed in the reaction in step 3 they arecalled intermediates In a complex reaction an intermediate is a substanceproduced in one elementary step and consumed in a subsequent elementarystep Catalysts and intermediates do not appear in the net chemical equation

For that reason the slowest of the elementary steps in a complex reaction iscalled the rate-determining step Figure 17-16 illustrates this concept in amanufacturing plant

Although the first and third elementary steps occur relatively fast the mid-dle step is the slowest and it limits the overall reaction rate It is the rate-determining step The relative energy levels of reactants intermediatesproducts and activated complex are illustrated in Figure 17-17

Chemists can make use of instantaneous reaction rates reaction ordersand rate-determining steps to develop efficient ways to manufacture prod-ucts such as pharmaceuticals By knowing which step of the reaction is slow-est a chemist can work to speed up that rate-determining step and therebyincrease the rate of the overall reaction

In many models of catalytic converters this inner structure resembles tubes in a honeycomb arrangement which provides significant surface area to accommodate the catalysts

At high temperatures (300ndash500C) on the platinum catalyst surface the dangerous carbon monoxide and hydrocarbons react with oxygen to form the compounds carbon dioxide and water

Inside the catalytic converter is a porous ceramic structure with a surface coating of platinum and rhodium particles

5 At the rhodium catalyst surface nitric oxide is converted to nitrogen and oxygen

Gasesfrom the engine and the air pass through the exhaust system to the catalytic converter Oxygen intake into the engine at this point is critical for the reactions of the catalysts

Catalytic ConverterConcerns for our environment have made a hugeimpact in the products and processes we use every dayThe catalytic converter is one of those impacts

When a combustion engine converts fuel into ener-gy the reactions of the combustion process are incom-plete Incomplete combustion results in the productionof poisonous carbon monoxide and undesirable nitro-gen oxides Since 1975 catalytic converters havereduced the exhaust emissions that contribute to airpollution by approximately 90

Summary171 A Model for Reaction Ratesbull The rate of a chemical reaction is expressed as the

rate at which a reactant is consumed or the rate atwhich a product is formed

bull Reaction rates are generally calculated and expressedin moles per liter per second (mol(Lmiddots))

bull In order to react the particles in a chemical reactionmust collide in a correct orientation and with suffi-cient energy to form the activated complex

bull The rate of a chemical reaction is unrelated to thespontaneity of the reaction

172 Factors Affecting Reaction Ratesbull Key factors that influence the rate of chemical reac-

tions include reactivity concentration surface areatemperature and catalysts

bull Catalysts increase the rates of chemical reactions bylowering activation energies

bull Raising the temperature of a reaction increases therate of the reaction by increasing the collision fre-quency and the number of collisions forming theactivated complex

173 Reaction Rate Lawsbull The mathematical relationship between the rate of a

chemical reaction at a given temperature and theconcentrations of reactants is called the rate law

bull The rate law for a chemical reaction is determinedexperimentally using the method of initial rates

174 Instantaneous Reaction Rates andReaction Mechanisms

bull The instantaneous rate for a chemical reaction iscalculated from the rate law the specific rate con-stant and the concentrations of all reactants

bull Most chemical reactions are complex reactions con-sisting of two or more elementary steps

bull A reaction mechanism is the complete sequence ofelementary steps that make up a complex reaction

Activation energy and reaction The collision depicted in Figure 17-3ddoes not lead to a reaction for a different reason Although the CO and NO2molecules collide with a favorable orientation no reaction occurs becausethey collide with insufficient energy to form the activated complex The min-imum amount of energy that reacting particles must have to form the acti-vated complex and lead to a reaction is called the activation energy Ea

Activation energy has a direct influence on the rate of a reaction A highEa means that relatively few collisions will have the required energy to pro-duce the activated complex and the reaction rate will be low On the otherhand a low Ea means that more collisions will have sufficient energy toreact and the reaction rate will be higher The problem-solving LAB belowemphasizes this fact It might be helpful to think of this relationship in termsof a person pushing a heavy cart up a hill If the hill is high a substantialamount of energy and effort will be required to move the cart and it will takea long time to get it to the top If the hill is low less energy will be requiredand the task will be accomplished faster

Figure 17-4 shows the energy diagram for the progress of the reactionbetween carbon monoxide and nitrogen dioxide Does this energy diagramlook somewhat different from those you studied in Chapter 16 Why Inaddition to the energies of the reactants and products this diagram shows theactivation energy of the reaction Activation energy can be thought of as abarrier the reactants must overcome in order to form the products In thiscase the CO and NO2 molecules collide with enough energy to overcome thebarrier and the products formed lie at a lower energy level Do you recall thatreactions that lose energy such as this example are called exothermic reactions

For many reactions the process from reactants to products is reversibleFigure 17-5 shows the reverse endothermic reaction between CO2 and NOto reform CO and NO2 In this reverse reaction the reactants which are themolecules that were formed in the exothermic forward reaction lie at a lowenergy level and must overcome a significant activation energy to reform COand NO2 This requires an input of energy If this reverse reaction isachieved CO and NO2 again lie at a high energy level

The influence of spontaneity Recall from Chapter 16 that reaction spon-taneity is related to change in free energy G If G is negative the reac-tion is spontaneous under the conditions specified If G is positive thereaction is not spontaneous Letrsquos now consider whether spontaneity has anyeffect on reaction rates Are more spontaneous reactions faster than lessspontaneous ones

To investigate the relationship between spontaneity and reaction rate con-sider the following gas-phase reaction between hydrogen and oxygen

2H2(g) O2(g) 0 2H2O(g)

Here G 458 kJ at 298 K (25degC) and 1 atm pressure Because G isnegative the reaction is spontaneous For the same reaction H 484 kJ which means that the reaction is highly exothermic You canexamine the speed of this reaction by filling a tape-wrapped soda bottle withstoichiometric quantities of the two gasesmdashtwo volumes hydrogen and onevolume oxygen A thermometer in the stopper allows you to monitor thetemperature inside the bottle As you watch for evidence of a reaction thetemperature remains constant for hours Have the gases escaped Or havethey simply failed to react If you remove the stopper and hold a burningsplint to the mouth of the bottle a reaction occurs explosively Clearly thehydrogen and oxygen gases have not escaped from the bottle Yet they didnot react noticeably until you supplied additional energy in the form of alighted splint The example shown in Figure 17-6 illustrates this same phe-nomenon The soap bubbles you see billowing from the bowl are filled withhydrogen When the lighted splint introduces additional energy an explo-sive reaction occurs between the hydrogen that was contained in the bub-bles and oxygen in the air

As these examples show reaction spontaneity in the form of G impliesabsolutely nothing about the speed of the reaction G merely indicates thenatural tendency for a reaction or process to proceed Factors other thanspontaneity however do affect the rate of a chemical reaction These factorsare keys in controlling and using the power of chemistry

Factors Affecting ReactionRates

Vocabulary catalystinhibitorheterogeneous catalysthomogeneous catalyst

According to the collision theory chemical reactions occur when moleculescollide in a particular orientation and with sufficient energy to achieve acti-vation energy You can probably identify chemical reactions that occur fastsuch as gasoline combustion and others that occur more slowly such as ironrusting But can the reaction rate of any single reaction vary or is the reac-tion rate constant regardless of the conditions In this section you will learnthat the reaction rate for almost any chemical reaction can be modified byvarying the conditions of the reaction

The Nature of ReactantsAn important factor that affects the rate of a chemical reaction is the reactivenature of the reactants As you know some substances react more readily thanothers For example calcium and sodium are both reactive metals howeverwhat happens when each metal is added to water is distinctly different Whena small piece of calcium is placed in cold water as shown in Figure 17-7athe calcium and water react slowly to form hydrogen gas and aqueous calci-um hydroxide

Ca(s) 2H2O(l) 0 H2(g) Ca(OH)2(aq)

When a small piece of sodium is placed in cold water the sodium and waterreact quickly to form hydrogen gas and aqueous sodium hydroxide as shownin Figure 17-7b

2Na(s) 2H2O(l) 0 H2(g) 2NaOH(aq)

Comparing the two equations itrsquos evident that the reactions are similarHowever the reaction between sodium and water occurs much fasterbecause sodium is more reactive with water than calcium is In fact the reac-tion releases so much heat so quickly that the hydrogen gas ignites as it isformed

ConcentrationReactions speed up when the concentrations of reacting particles areincreased One of the fundamental principles of the collision theory is thatparticles must collide to react The number of particles in a reaction makes adifference in the rate at which the reaction takes place Think about a reac-tion where reactant A combines with reactant B At a given concentration ofA and B the molecules of A collide with B to produce AB at a particular rateWhat happens if the amount of B is increased Increasing the concentrationof B makes more molecules available with which A can collide Reactant Aldquofindsrdquo reactant B more easily because there are more B molecules in thearea which increases probability of collision and ultimately increases therate of reaction between A and B

Look at the two reactions shown in Figure 17-8 Steel wool is first heat-ed over a burner until it is red hot In Figure 17-8a the hot steel wool reactswith oxygen in the air How does this reaction compare with the one inFigure 17-8b in which the hot steel wool is lowered immediately into a flaskcontaining nearly 100 percent oxygenmdashapproximately five times the concen-tration of oxygen in air Applying the collision theory to this reaction thehigher concentration of oxygen increases the collision frequency betweeniron atoms and oxygen molecules which increases the rate of the reaction

If you have ever been near a person using bottled oxygen or seen an oxy-gen generator you may have noticed a sign cautioning against smoking orusing open flames Can you now explain the reason for the caution noticeThe high concentration of oxygen could cause a combustion reaction to occurat an explosive rate The CHEMLAB at the end of this chapter gives you anopportunity to further investigate the effect of concentration on reaction rates

Surface AreaNow suppose you were to lower a red-hot chunk of steel instead of steelwool into a flask of oxygen gas The oxygen would react with the steel muchmore slowly than it would with the steel wool Using what you know aboutthe collision theory can you explain why You are correct if you said thatfor the same mass of iron steel wool has much more surface area than thechunk of steel The greater surface area of the steel wool allows the oxygenmolecules to collide with many more iron atoms per unit of time

172 Factors Affecting Reaction Rates 537

Figure 17-8

The concentration of oxygenin the air surrounding the steelwool is much less than that ofthe pure oxygen in the flask

The higher oxygen concen-tration accounts for the fasterreaction

Pulverizing (or grinding) a substance is one way to increase its rate ofreaction This is because for the same mass many small particles possessmore total surface area than one large particle So a spoonful of granulatedsugar placed in a cup of water dissolves faster than the same mass of sugarin a single chunk which has less surface area as shown in Figure 17-9 Thisexample illustrates that increasing the surface area of a reactant does notchange its concentration but it does increase the rate of reaction by increas-ing the collision rate between reacting particles

TemperatureGenerally increasing the temperature at which a reaction occurs increasesthe reaction rate For example you know that the reactions that cause foodsto spoil occur much faster at room temperature than when the foods arerefrigerated The graph in Figure 17-10a illustrates that increasing the tem-perature by 10 K can approximately double the rate of a reaction How cana small increase in temperature have such a significant effect

As you learned in Chapter 13 increasing the temperature of a substanceincreases the average kinetic energy of the particles that make up the sub-stance For that reason reacting particles collide more frequently at highertemperatures than at lower temperatures However that fact alone doesnrsquotaccount for the increase in reaction rate with increasing temperature To bet-ter understand how reaction rate varies with temperature examine the graphshown in Figure 17-10b This graph compares the numbers of particles hav-ing sufficient energy to react at temperatures T1 and T2 where T2 is greaterthan T1 The shaded area under each curve represents the number of colli-sions having energy equal to or greater than the activation energy The dot-ted line indicates the activation energy (Ea) for the reaction How do theshaded areas compare The number of high-energy collisions at the highertemperature T2 is much greater than at the lower temperature T1 Thereforeas the temperature increases more collisions result in a reaction

As you can see increasing the temperature of the reactants increases thereaction rate because raising the kinetic energy of the reacting particles rais-es both the collision frequency and the collision energy You can investigatethe relationship between reaction rate and temperature by performing theminiLAB for this chapter

CatalystsYoursquove seen that increasing the temperature andor the concentration of reac-tants can dramatically increase the rate of a reaction However an increasein temperature is not always the best (or most practical) thing to do Forexample suppose that you want to increase the rate of a reaction such as thedecomposition of glucose in a living cell Increasing the temperature andorthe concentration of reactants is not a viable alternative because it mightharm or kill the cell

It is a fact that many chemical reactions in living organisms would notoccur quickly enough to sustain life at normal living temperatures if it werenot for the presence of enzymes An enzyme is a type of catalyst a sub-stance that increases the rate of a chemical reaction without itself being con-sumed in the reaction Although catalysts are important substances in achemical reaction a catalyst does not yield more product and is not includ-ed in the product(s) of the reaction In fact catalysts are not included in thechemical equation

Compare the amount of time itwould take this train to travelover or around the barrier withthe time it takes to travelthrough the barrier Obviouslytravel is faster through themountain with the aid of thetunnel

Note that the activation energy for the catalyzed reaction is much lower thanfor the uncatalyzed reaction The lower activation energy for the catalyzedreaction means that more collisions have sufficient energy to initiate reac-tion It might help you to visualize this relationship by thinking of the reac-tionrsquos activation energy as a mountain range to be crossed as shown inFigure 17-12 In this analogy the tunnel representing the catalyzed path-way provides an easier and therefore quicker route to the other side of themountains

Another type of substance that affects reaction rates is called an inhibitorUnlike a catalyst which speeds up reaction rates an inhibitor is a substancethat slows down or inhibits reaction rates Some inhibitors in fact actuallyprevent a reaction from happening at all

In our fast-paced world it might seem unlikely that it would be desirableto slow a reaction But if you think about your environment you can proba-bly come up with several uses for inhibitors One of the primary applicationsfor inhibitors is in the food industry where inhibitors are called preserva-tives Figure 17-13 shows how a commercially available fruit freshener

Heterogeneous and homogeneous catalysts In order to reduce harm-ful engine emissions automobiles manufactured today must have catalyticconverters similar to the one described in How It Works at the end of thechapter The most effective catalysts for this application are transition metaloxides and metals such as palladium and platinum These substances catalyzereactions that convert nitrogen monoxide to nitrogen and oxygen carbonmonoxide to carbon dioxide and unburned gasoline to carbon dioxide andwater Because the catalysts in a catalytic converter are solids and the reac-tions they catalyze are gaseous the catalysts are called heterogeneous cata-lysts A heterogeneous catalyst exists in a physical state different than thatof the reaction it catalyzes A catalyst that exists in the same physical state asthe reaction it catalyzes is called a homogeneous catalyst For example ifboth an enzyme and the reaction it catalyzes are in aqueous solution theenzyme is a homogeneous catalyst

Section 173 Reaction Rate Laws

Objectivesbull Express the relationship

between reaction rate andconcentration

bull Determine reaction ordersusing the method of initialrates

Vocabulary rate lawspecific rate constantreaction ordermethod of initial rates

In Section 171 you learned how to calculate the average rate of a chemicalreaction given the initial and final times and concentrations The word aver-age is important because most chemical reactions slow down as the reactantsare consumed To understand why most reaction rates slow over time recallthat the collision theory states that chemical reactions can occur only whenthe reacting particles collide and that reaction rate depends upon reactantconcentration As reactants are consumed fewer particles collide and thereaction slows Chemists use the concept of rate laws to quantify the resultsof the collision theory in terms of a mathematical relationship between therate of a chemical reaction and the reactant concentration

Reaction Rate LawsThe equation that expresses the mathematical relationship between the rateof a chemical reaction and the concentration of reactants is called a rate lawFor example the reaction A 0 B which is a one-step reaction has only oneactivated complex between reactants and products The rate law for this reac-tion is expressed as

where k is the specific rate constant or a numerical value that relates reac-tion rate and concentration of reactants at a given temperature Units for therate constant include L(mols) L2(mol2s) and sndash1 Depending on the reac-tion conditions especially temperature k is unique for every reaction

The rate law means that the reaction rate is directly proportional to the molarconcentration of A Thus doubling the concentration of A will double the reac-tion rate Increasing the concentration of A by a factor of 5 will increase thereaction rate by a factor of 5 The specific rate constant k does not change withconcentration however k does change with temperature A large value of kmeans that A reacts rapidly to form B What does a small value of k mean

Reaction order In the expression Rate k[A] it is understood that thenotation [A] means the same as [A]1 In other words for reactant A theunderstood exponent 1 is called the reaction order The reaction order for areactant defines how the rate is affected by the concentration of that reactantFor example the rate law for the decomposition of H2O2 is expressed by thefollowing equation

Rate k[H2O2]

Because the reaction rate is directly proportional to the concentration ofH2O2 raised to the first power [H2O2]

1 the decomposition of H2O2 is said tobe first order in H2O2 Because the reaction is first order in H2O2 the reac-tion rate changes in the same proportion that the concentration of H2O2changes So if the H2O2 concentration decreases to one-half its originalvalue the reaction rate is halved as well

Recall from Section 171 that reaction rates are determined from experi-mental data Because reaction order is based on reaction rates it follows thatreaction order also is determined experimentally Finally because the rateconstant describes the reaction rate k too must be determined experimen-tally Figure 17-14 illustrates two of several experimental methods that arecommonly used to measure reaction rates

Other reaction orders The overall reaction order of a chemical reactionis the sum of the orders for the individual reactants in the rate law Manychemical reactions particularly those having more than one reactant are notfirst order Consider the general form for a chemical reaction with two reac-tants In this chemical equation a and b are coefficients

aA bB 0 products

The general rate law for such a reaction is

Rate k[A]m[B]n

where m and n are the reaction orders for A and B respectively Only if thereaction between A and B occurs in a single step (and with a single activat-ed complex) does m a and n b Thatrsquos unlikely however because sin-gle-step reactions are uncommon

For example the reaction between nitrogen monoxide (NO) and hydrogen(H2) is described by the following equation

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

This reaction which occurs in more than one step has the following rate law

Rate k[NO]2[H2]

This rate law was determined experimentally The data tell that the ratedepends on the concentration of the reactants as follows If [NO] doubles therate quadruples if [H2] doubles the rate doubles The reaction is describedas second order in NO first order in H2 and third order overall because thesum of the orders for the individual reactants (the sum of the exponents) is(2 1) or 3

Determining Reaction OrderOne common experimental method of evaluating reaction order is called themethod of initial rates The method of initial rates determines reactionorder by comparing the initial rates of a reaction carried out with varyingreactant concentrations To understand how this method works letrsquos use thegeneral reaction aA bB 0 products Suppose that this reaction is carriedout with varying concentrations of A and B and yields the initial reactionrates shown in Table 17-3

Recall that the general rate law for this type of reaction is

Rate k[A]m[B]n

To determine m the concentrations and reaction rates in Trials 1 and 2 arecompared As you can see from the data while the concentration of Bremains constant the concentration of A in Trial 2 is twice that of Trial 1Note that the initial rate in Trial 2 is twice that of Trial 1 Because doubling[A] doubles the rate the reaction must be first order in A That is because2m 2 m must equal 1 The same method is used to determine n only thistime Trials 2 and 3 are compared Doubling the concentration of B causes therate to increase by four times Because 2n 4 n must equal 2 This infor-mation suggests that the reaction is second order in B giving the followingoverall rate law

Rate k[A]1[B]2

The overall reaction order is third order (sum of exponents 2 1 3)

The average reaction rate you learned to calculate in Section 173 givesimportant information about the reaction over a period of time Howeverchemists also may need to know at what rate the reaction is proceeding at aspecific time A pharmacist developing a new drug treatment might need toknow the progress of a reaction at an exact instant This information makesit possible to adjust the product for maximum performance Can you think ofother situations where it might be critical to know the specific reaction rateat a given time

Instantaneous Reaction RatesThe decomposition of hydrogen peroxide (H2O2) is represented as follows

2H2O2(aq) 0 2H2O(l) O2(g)

For this reaction the decrease in H2O2 concentration over time is shown inFigure 17-15 The curved line shows how the reaction rate decreases as thereaction proceeds The instantaneous rate or the rate of decomposition ata specific time can be determined by finding the slope of the straight linetangent to the curve at that instant This is because the slope of the tangentto the curve at a particular point is [H2O2]t which is one way to expressthe reaction rate In other words the rate of change in H2O2 concentrationrelates to one specific point (or instant) on the graph

Another way to determine the instantaneous rate for a chemical reactionis to use the experimentally determined rate law given the reactant concen-trations and the specific rate constant for the temperature at which the reactionoccurs For example the decomposition of dinitrogen pentoxide (N2O5) intonitrogen dioxide (NO2) and oxygen (O2) is given by the following equation

2 Ultraviolet radiation causes the decomposition reaction O3 0 O2 O

3 ClO produced in the reaction in step 1 reacts with O produced in step 2according to the equation ClO O 0 Cl O2

Each of the reactions described in steps 1 through 3 is called an elementarystep These three elementary steps comprise the complex reaction 2O3 0 3O2A complex reaction is one that consists of two or more elementary steps Thecomplete sequence of elementary steps that make up a complex reaction iscalled a reaction mechanism Adding the elementary steps in steps 1 through3 and canceling formulas that occur in equal amounts on both sides of the reac-tion arrow produce the net equation for the complex reaction as shown below

Elementary step Cl O3 0 O2 ClO

Elementary step ClO O 0 Cl O2

Complex reaction 2O3 0 3O2

Because chlorine atoms react in step 1 of the reaction mechanism and arere-formed in step 3 chlorine is said to catalyze the decomposition of ozoneDo you know why Because ClO and O are formed in the reactions in steps1 and 2 respectively and are consumed in the reaction in step 3 they arecalled intermediates In a complex reaction an intermediate is a substanceproduced in one elementary step and consumed in a subsequent elementarystep Catalysts and intermediates do not appear in the net chemical equation

Rate-determining step You have probably heard the expression ldquoAchain is no stronger than its weakest linkrdquo Chemical reactions too have aldquoweakest linkrdquo in that a complex reaction can proceed no faster than theslowest of its elementary steps In other words the slowest elementary stepin a reaction mechanism limits the instantaneous rate of the overall reaction

For that reason the slowest of the elementary steps in a complex reaction iscalled the rate-determining step Figure 17-16 illustrates this concept in amanufacturing plant

N2O2 H2 0 N2O H2O (slow)

N2O H2 0 N2 H2O (fast)

Although the first and third elementary steps occur relatively fast the mid-dle step is the slowest and it limits the overall reaction rate It is the rate-determining step The relative energy levels of reactants intermediatesproducts and activated complex are illustrated in Figure 17-17

Chemists can make use of instantaneous reaction rates reaction ordersand rate-determining steps to develop efficient ways to manufacture prod-ucts such as pharmaceuticals By knowing which step of the reaction is slow-est a chemist can work to speed up that rate-determining step and therebyincrease the rate of the overall reaction

In many models of catalytic converters this inner structure resembles tubes in a honeycomb arrangement which provides significant surface area to accommodate the catalysts

At high temperatures (300ndash500C) on the platinum catalyst surface the dangerous carbon monoxide and hydrocarbons react with oxygen to form the compounds carbon dioxide and water

Inside the catalytic converter is a porous ceramic structure with a surface coating of platinum and rhodium particles

5 At the rhodium catalyst surface nitric oxide is converted to nitrogen and oxygen

Gasesfrom the engine and the air pass through the exhaust system to the catalytic converter Oxygen intake into the engine at this point is critical for the reactions of the catalysts

Catalytic ConverterConcerns for our environment have made a hugeimpact in the products and processes we use every dayThe catalytic converter is one of those impacts

When a combustion engine converts fuel into ener-gy the reactions of the combustion process are incom-plete Incomplete combustion results in the productionof poisonous carbon monoxide and undesirable nitro-gen oxides Since 1975 catalytic converters havereduced the exhaust emissions that contribute to airpollution by approximately 90

Key Equations and Relationships

Summary171 A Model for Reaction Ratesbull The rate of a chemical reaction is expressed as the

rate at which a reactant is consumed or the rate atwhich a product is formed

bull Reaction rates are generally calculated and expressedin moles per liter per second (mol(Lmiddots))

bull In order to react the particles in a chemical reactionmust collide in a correct orientation and with suffi-cient energy to form the activated complex

bull The rate of a chemical reaction is unrelated to thespontaneity of the reaction

172 Factors Affecting Reaction Ratesbull Key factors that influence the rate of chemical reac-

tions include reactivity concentration surface areatemperature and catalysts

bull Catalysts increase the rates of chemical reactions bylowering activation energies

bull Raising the temperature of a reaction increases therate of the reaction by increasing the collision fre-quency and the number of collisions forming theactivated complex

173 Reaction Rate Lawsbull The mathematical relationship between the rate of a

chemical reaction at a given temperature and theconcentrations of reactants is called the rate law

bull The rate law for a chemical reaction is determinedexperimentally using the method of initial rates

174 Instantaneous Reaction Rates andReaction Mechanisms

bull The instantaneous rate for a chemical reaction iscalculated from the rate law the specific rate con-stant and the concentrations of all reactants

bull Most chemical reactions are complex reactions con-sisting of two or more elementary steps

bull A reaction mechanism is the complete sequence ofelementary steps that make up a complex reaction

bull For a complex reaction the rate-determining steplimits the instantaneous rate of the overall reaction

Figure 17-4 shows the energy diagram for the progress of the reactionbetween carbon monoxide and nitrogen dioxide Does this energy diagramlook somewhat different from those you studied in Chapter 16 Why Inaddition to the energies of the reactants and products this diagram shows theactivation energy of the reaction Activation energy can be thought of as abarrier the reactants must overcome in order to form the products In thiscase the CO and NO2 molecules collide with enough energy to overcome thebarrier and the products formed lie at a lower energy level Do you recall thatreactions that lose energy such as this example are called exothermic reactions

For many reactions the process from reactants to products is reversibleFigure 17-5 shows the reverse endothermic reaction between CO2 and NOto reform CO and NO2 In this reverse reaction the reactants which are themolecules that were formed in the exothermic forward reaction lie at a lowenergy level and must overcome a significant activation energy to reform COand NO2 This requires an input of energy If this reverse reaction isachieved CO and NO2 again lie at a high energy level

The influence of spontaneity Recall from Chapter 16 that reaction spon-taneity is related to change in free energy G If G is negative the reac-tion is spontaneous under the conditions specified If G is positive thereaction is not spontaneous Letrsquos now consider whether spontaneity has anyeffect on reaction rates Are more spontaneous reactions faster than lessspontaneous ones

To investigate the relationship between spontaneity and reaction rate con-sider the following gas-phase reaction between hydrogen and oxygen

2H2(g) O2(g) 0 2H2O(g)

Here G 458 kJ at 298 K (25degC) and 1 atm pressure Because G isnegative the reaction is spontaneous For the same reaction H 484 kJ which means that the reaction is highly exothermic You canexamine the speed of this reaction by filling a tape-wrapped soda bottle withstoichiometric quantities of the two gasesmdashtwo volumes hydrogen and onevolume oxygen A thermometer in the stopper allows you to monitor thetemperature inside the bottle As you watch for evidence of a reaction thetemperature remains constant for hours Have the gases escaped Or havethey simply failed to react If you remove the stopper and hold a burningsplint to the mouth of the bottle a reaction occurs explosively Clearly thehydrogen and oxygen gases have not escaped from the bottle Yet they didnot react noticeably until you supplied additional energy in the form of alighted splint The example shown in Figure 17-6 illustrates this same phe-nomenon The soap bubbles you see billowing from the bowl are filled withhydrogen When the lighted splint introduces additional energy an explo-sive reaction occurs between the hydrogen that was contained in the bub-bles and oxygen in the air

As these examples show reaction spontaneity in the form of G impliesabsolutely nothing about the speed of the reaction G merely indicates thenatural tendency for a reaction or process to proceed Factors other thanspontaneity however do affect the rate of a chemical reaction These factorsare keys in controlling and using the power of chemistry

Factors Affecting ReactionRates

Vocabulary catalystinhibitorheterogeneous catalysthomogeneous catalyst

According to the collision theory chemical reactions occur when moleculescollide in a particular orientation and with sufficient energy to achieve acti-vation energy You can probably identify chemical reactions that occur fastsuch as gasoline combustion and others that occur more slowly such as ironrusting But can the reaction rate of any single reaction vary or is the reac-tion rate constant regardless of the conditions In this section you will learnthat the reaction rate for almost any chemical reaction can be modified byvarying the conditions of the reaction

The Nature of ReactantsAn important factor that affects the rate of a chemical reaction is the reactivenature of the reactants As you know some substances react more readily thanothers For example calcium and sodium are both reactive metals howeverwhat happens when each metal is added to water is distinctly different Whena small piece of calcium is placed in cold water as shown in Figure 17-7athe calcium and water react slowly to form hydrogen gas and aqueous calci-um hydroxide

Ca(s) 2H2O(l) 0 H2(g) Ca(OH)2(aq)

When a small piece of sodium is placed in cold water the sodium and waterreact quickly to form hydrogen gas and aqueous sodium hydroxide as shownin Figure 17-7b

2Na(s) 2H2O(l) 0 H2(g) 2NaOH(aq)

Comparing the two equations itrsquos evident that the reactions are similarHowever the reaction between sodium and water occurs much fasterbecause sodium is more reactive with water than calcium is In fact the reac-tion releases so much heat so quickly that the hydrogen gas ignites as it isformed

ConcentrationReactions speed up when the concentrations of reacting particles areincreased One of the fundamental principles of the collision theory is thatparticles must collide to react The number of particles in a reaction makes adifference in the rate at which the reaction takes place Think about a reac-tion where reactant A combines with reactant B At a given concentration ofA and B the molecules of A collide with B to produce AB at a particular rateWhat happens if the amount of B is increased Increasing the concentrationof B makes more molecules available with which A can collide Reactant Aldquofindsrdquo reactant B more easily because there are more B molecules in thearea which increases probability of collision and ultimately increases therate of reaction between A and B

Look at the two reactions shown in Figure 17-8 Steel wool is first heat-ed over a burner until it is red hot In Figure 17-8a the hot steel wool reactswith oxygen in the air How does this reaction compare with the one inFigure 17-8b in which the hot steel wool is lowered immediately into a flaskcontaining nearly 100 percent oxygenmdashapproximately five times the concen-tration of oxygen in air Applying the collision theory to this reaction thehigher concentration of oxygen increases the collision frequency betweeniron atoms and oxygen molecules which increases the rate of the reaction

If you have ever been near a person using bottled oxygen or seen an oxy-gen generator you may have noticed a sign cautioning against smoking orusing open flames Can you now explain the reason for the caution noticeThe high concentration of oxygen could cause a combustion reaction to occurat an explosive rate The CHEMLAB at the end of this chapter gives you anopportunity to further investigate the effect of concentration on reaction rates

Surface AreaNow suppose you were to lower a red-hot chunk of steel instead of steelwool into a flask of oxygen gas The oxygen would react with the steel muchmore slowly than it would with the steel wool Using what you know aboutthe collision theory can you explain why You are correct if you said thatfor the same mass of iron steel wool has much more surface area than thechunk of steel The greater surface area of the steel wool allows the oxygenmolecules to collide with many more iron atoms per unit of time

172 Factors Affecting Reaction Rates 537

Figure 17-8

The concentration of oxygenin the air surrounding the steelwool is much less than that ofthe pure oxygen in the flask

The higher oxygen concen-tration accounts for the fasterreaction

Pulverizing (or grinding) a substance is one way to increase its rate ofreaction This is because for the same mass many small particles possessmore total surface area than one large particle So a spoonful of granulatedsugar placed in a cup of water dissolves faster than the same mass of sugarin a single chunk which has less surface area as shown in Figure 17-9 Thisexample illustrates that increasing the surface area of a reactant does notchange its concentration but it does increase the rate of reaction by increas-ing the collision rate between reacting particles

TemperatureGenerally increasing the temperature at which a reaction occurs increasesthe reaction rate For example you know that the reactions that cause foodsto spoil occur much faster at room temperature than when the foods arerefrigerated The graph in Figure 17-10a illustrates that increasing the tem-perature by 10 K can approximately double the rate of a reaction How cana small increase in temperature have such a significant effect

As you learned in Chapter 13 increasing the temperature of a substanceincreases the average kinetic energy of the particles that make up the sub-stance For that reason reacting particles collide more frequently at highertemperatures than at lower temperatures However that fact alone doesnrsquotaccount for the increase in reaction rate with increasing temperature To bet-ter understand how reaction rate varies with temperature examine the graphshown in Figure 17-10b This graph compares the numbers of particles hav-ing sufficient energy to react at temperatures T1 and T2 where T2 is greaterthan T1 The shaded area under each curve represents the number of colli-sions having energy equal to or greater than the activation energy The dot-ted line indicates the activation energy (Ea) for the reaction How do theshaded areas compare The number of high-energy collisions at the highertemperature T2 is much greater than at the lower temperature T1 Thereforeas the temperature increases more collisions result in a reaction

As you can see increasing the temperature of the reactants increases thereaction rate because raising the kinetic energy of the reacting particles rais-es both the collision frequency and the collision energy You can investigatethe relationship between reaction rate and temperature by performing theminiLAB for this chapter

CatalystsYoursquove seen that increasing the temperature andor the concentration of reac-tants can dramatically increase the rate of a reaction However an increasein temperature is not always the best (or most practical) thing to do Forexample suppose that you want to increase the rate of a reaction such as thedecomposition of glucose in a living cell Increasing the temperature andorthe concentration of reactants is not a viable alternative because it mightharm or kill the cell

It is a fact that many chemical reactions in living organisms would notoccur quickly enough to sustain life at normal living temperatures if it werenot for the presence of enzymes An enzyme is a type of catalyst a sub-stance that increases the rate of a chemical reaction without itself being con-sumed in the reaction Although catalysts are important substances in achemical reaction a catalyst does not yield more product and is not includ-ed in the product(s) of the reaction In fact catalysts are not included in thechemical equation

Compare the amount of time itwould take this train to travelover or around the barrier withthe time it takes to travelthrough the barrier Obviouslytravel is faster through themountain with the aid of thetunnel

Note that the activation energy for the catalyzed reaction is much lower thanfor the uncatalyzed reaction The lower activation energy for the catalyzedreaction means that more collisions have sufficient energy to initiate reac-tion It might help you to visualize this relationship by thinking of the reac-tionrsquos activation energy as a mountain range to be crossed as shown inFigure 17-12 In this analogy the tunnel representing the catalyzed path-way provides an easier and therefore quicker route to the other side of themountains

Another type of substance that affects reaction rates is called an inhibitorUnlike a catalyst which speeds up reaction rates an inhibitor is a substancethat slows down or inhibits reaction rates Some inhibitors in fact actuallyprevent a reaction from happening at all

In our fast-paced world it might seem unlikely that it would be desirableto slow a reaction But if you think about your environment you can proba-bly come up with several uses for inhibitors One of the primary applicationsfor inhibitors is in the food industry where inhibitors are called preserva-tives Figure 17-13 shows how a commercially available fruit freshener

Heterogeneous and homogeneous catalysts In order to reduce harm-ful engine emissions automobiles manufactured today must have catalyticconverters similar to the one described in How It Works at the end of thechapter The most effective catalysts for this application are transition metaloxides and metals such as palladium and platinum These substances catalyzereactions that convert nitrogen monoxide to nitrogen and oxygen carbonmonoxide to carbon dioxide and unburned gasoline to carbon dioxide andwater Because the catalysts in a catalytic converter are solids and the reac-tions they catalyze are gaseous the catalysts are called heterogeneous cata-lysts A heterogeneous catalyst exists in a physical state different than thatof the reaction it catalyzes A catalyst that exists in the same physical state asthe reaction it catalyzes is called a homogeneous catalyst For example ifboth an enzyme and the reaction it catalyzes are in aqueous solution theenzyme is a homogeneous catalyst

In Section 171 you learned how to calculate the average rate of a chemicalreaction given the initial and final times and concentrations The word aver-age is important because most chemical reactions slow down as the reactantsare consumed To understand why most reaction rates slow over time recallthat the collision theory states that chemical reactions can occur only whenthe reacting particles collide and that reaction rate depends upon reactantconcentration As reactants are consumed fewer particles collide and thereaction slows Chemists use the concept of rate laws to quantify the resultsof the collision theory in terms of a mathematical relationship between therate of a chemical reaction and the reactant concentration

Reaction Rate LawsThe equation that expresses the mathematical relationship between the rateof a chemical reaction and the concentration of reactants is called a rate lawFor example the reaction A 0 B which is a one-step reaction has only oneactivated complex between reactants and products The rate law for this reac-tion is expressed as

where k is the specific rate constant or a numerical value that relates reac-tion rate and concentration of reactants at a given temperature Units for therate constant include L(mols) L2(mol2s) and sndash1 Depending on the reac-tion conditions especially temperature k is unique for every reaction

The rate law means that the reaction rate is directly proportional to the molarconcentration of A Thus doubling the concentration of A will double the reac-tion rate Increasing the concentration of A by a factor of 5 will increase thereaction rate by a factor of 5 The specific rate constant k does not change withconcentration however k does change with temperature A large value of kmeans that A reacts rapidly to form B What does a small value of k mean

Reaction order In the expression Rate k[A] it is understood that thenotation [A] means the same as [A]1 In other words for reactant A theunderstood exponent 1 is called the reaction order The reaction order for areactant defines how the rate is affected by the concentration of that reactantFor example the rate law for the decomposition of H2O2 is expressed by thefollowing equation

Rate k[H2O2]

Because the reaction rate is directly proportional to the concentration ofH2O2 raised to the first power [H2O2]

1 the decomposition of H2O2 is said tobe first order in H2O2 Because the reaction is first order in H2O2 the reac-tion rate changes in the same proportion that the concentration of H2O2changes So if the H2O2 concentration decreases to one-half its originalvalue the reaction rate is halved as well

Recall from Section 171 that reaction rates are determined from experi-mental data Because reaction order is based on reaction rates it follows thatreaction order also is determined experimentally Finally because the rateconstant describes the reaction rate k too must be determined experimen-tally Figure 17-14 illustrates two of several experimental methods that arecommonly used to measure reaction rates

Other reaction orders The overall reaction order of a chemical reactionis the sum of the orders for the individual reactants in the rate law Manychemical reactions particularly those having more than one reactant are notfirst order Consider the general form for a chemical reaction with two reac-tants In this chemical equation a and b are coefficients

aA bB 0 products

The general rate law for such a reaction is

Rate k[A]m[B]n

where m and n are the reaction orders for A and B respectively Only if thereaction between A and B occurs in a single step (and with a single activat-ed complex) does m a and n b Thatrsquos unlikely however because sin-gle-step reactions are uncommon

For example the reaction between nitrogen monoxide (NO) and hydrogen(H2) is described by the following equation

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

This reaction which occurs in more than one step has the following rate law

Rate k[NO]2[H2]

This rate law was determined experimentally The data tell that the ratedepends on the concentration of the reactants as follows If [NO] doubles therate quadruples if [H2] doubles the rate doubles The reaction is describedas second order in NO first order in H2 and third order overall because thesum of the orders for the individual reactants (the sum of the exponents) is(2 1) or 3

Determining Reaction OrderOne common experimental method of evaluating reaction order is called themethod of initial rates The method of initial rates determines reactionorder by comparing the initial rates of a reaction carried out with varyingreactant concentrations To understand how this method works letrsquos use thegeneral reaction aA bB 0 products Suppose that this reaction is carriedout with varying concentrations of A and B and yields the initial reactionrates shown in Table 17-3

Recall that the general rate law for this type of reaction is

Rate k[A]m[B]n

To determine m the concentrations and reaction rates in Trials 1 and 2 arecompared As you can see from the data while the concentration of Bremains constant the concentration of A in Trial 2 is twice that of Trial 1Note that the initial rate in Trial 2 is twice that of Trial 1 Because doubling[A] doubles the rate the reaction must be first order in A That is because2m 2 m must equal 1 The same method is used to determine n only thistime Trials 2 and 3 are compared Doubling the concentration of B causes therate to increase by four times Because 2n 4 n must equal 2 This infor-mation suggests that the reaction is second order in B giving the followingoverall rate law

Rate k[A]1[B]2

The overall reaction order is third order (sum of exponents 2 1 3)

The average reaction rate you learned to calculate in Section 173 givesimportant information about the reaction over a period of time Howeverchemists also may need to know at what rate the reaction is proceeding at aspecific time A pharmacist developing a new drug treatment might need toknow the progress of a reaction at an exact instant This information makesit possible to adjust the product for maximum performance Can you think ofother situations where it might be critical to know the specific reaction rateat a given time

Instantaneous Reaction RatesThe decomposition of hydrogen peroxide (H2O2) is represented as follows

2H2O2(aq) 0 2H2O(l) O2(g)

For this reaction the decrease in H2O2 concentration over time is shown inFigure 17-15 The curved line shows how the reaction rate decreases as thereaction proceeds The instantaneous rate or the rate of decomposition ata specific time can be determined by finding the slope of the straight linetangent to the curve at that instant This is because the slope of the tangentto the curve at a particular point is [H2O2]t which is one way to expressthe reaction rate In other words the rate of change in H2O2 concentrationrelates to one specific point (or instant) on the graph

Another way to determine the instantaneous rate for a chemical reactionis to use the experimentally determined rate law given the reactant concen-trations and the specific rate constant for the temperature at which the reactionoccurs For example the decomposition of dinitrogen pentoxide (N2O5) intonitrogen dioxide (NO2) and oxygen (O2) is given by the following equation

2NO(g) H2(g) 0 N2O(g) H2O(g)

Calculate the instantaneous rate when the reactant concentrations are[NO] = 000200M and [H2] = 000400M

3 Evaluate the AnswerAre the units correct Units in the calculation cancel to give mol(Lmiddots)which is the common unit for the expression of reaction rates Is themagnitude reasonable A magnitude of approximately 106 mol(Lmiddots)fits with the quantities given and the rate law equation

Reaction MechanismsMost chemical reactions consist of a sequence of two or more simpler reac-tions For example recent evidence indicates that the reaction 2O3 0 3O2occurs in three steps after intense ultraviolet radiation from the sun liberateschlorine atoms from certain compounds in Earthrsquos stratosphere Steps 1 and2 in this reaction may occur simultaneously or in reverse order

1 Chlorine atoms decompose ozone according to the equation Cl O3 0 O2 ClO

2 Ultraviolet radiation causes the decomposition reaction O3 0 O2 O

3 ClO produced in the reaction in step 1 reacts with O produced in step 2according to the equation ClO O 0 Cl O2

Each of the reactions described in steps 1 through 3 is called an elementarystep These three elementary steps comprise the complex reaction 2O3 0 3O2A complex reaction is one that consists of two or more elementary steps Thecomplete sequence of elementary steps that make up a complex reaction iscalled a reaction mechanism Adding the elementary steps in steps 1 through3 and canceling formulas that occur in equal amounts on both sides of the reac-tion arrow produce the net equation for the complex reaction as shown below

Elementary step Cl O3 0 O2 ClO

Elementary step O3 0 O2 O

Elementary step ClO O 0 Cl O2

Complex reaction 2O3 0 3O2

Because chlorine atoms react in step 1 of the reaction mechanism and arere-formed in step 3 chlorine is said to catalyze the decomposition of ozoneDo you know why Because ClO and O are formed in the reactions in steps1 and 2 respectively and are consumed in the reaction in step 3 they arecalled intermediates In a complex reaction an intermediate is a substanceproduced in one elementary step and consumed in a subsequent elementarystep Catalysts and intermediates do not appear in the net chemical equation

Rate-determining step You have probably heard the expression ldquoAchain is no stronger than its weakest linkrdquo Chemical reactions too have aldquoweakest linkrdquo in that a complex reaction can proceed no faster than theslowest of its elementary steps In other words the slowest elementary stepin a reaction mechanism limits the instantaneous rate of the overall reaction

For that reason the slowest of the elementary steps in a complex reaction iscalled the rate-determining step Figure 17-16 illustrates this concept in amanufacturing plant

To see how the rate-determining step affects reaction rate again considerthe gas-phase reaction between hydrogen and nitrogen monoxide discussedearlier in the chapter

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

A proposed mechanism for this reaction consists of the following elementarysteps

2NO 0 N2O2 (fast)

N2O2 H2 0 N2O H2O (slow)

N2O H2 0 N2 H2O (fast)

Although the first and third elementary steps occur relatively fast the mid-dle step is the slowest and it limits the overall reaction rate It is the rate-determining step The relative energy levels of reactants intermediatesproducts and activated complex are illustrated in Figure 17-17

Chemists can make use of instantaneous reaction rates reaction ordersand rate-determining steps to develop efficient ways to manufacture prod-ucts such as pharmaceuticals By knowing which step of the reaction is slow-est a chemist can work to speed up that rate-determining step and therebyincrease the rate of the overall reaction

The influence of spontaneity Recall from Chapter 16 that reaction spon-taneity is related to change in free energy G If G is negative the reac-tion is spontaneous under the conditions specified If G is positive thereaction is not spontaneous Letrsquos now consider whether spontaneity has anyeffect on reaction rates Are more spontaneous reactions faster than lessspontaneous ones

To investigate the relationship between spontaneity and reaction rate con-sider the following gas-phase reaction between hydrogen and oxygen

2H2(g) O2(g) 0 2H2O(g)

Here G 458 kJ at 298 K (25degC) and 1 atm pressure Because G isnegative the reaction is spontaneous For the same reaction H 484 kJ which means that the reaction is highly exothermic You canexamine the speed of this reaction by filling a tape-wrapped soda bottle withstoichiometric quantities of the two gasesmdashtwo volumes hydrogen and onevolume oxygen A thermometer in the stopper allows you to monitor thetemperature inside the bottle As you watch for evidence of a reaction thetemperature remains constant for hours Have the gases escaped Or havethey simply failed to react If you remove the stopper and hold a burningsplint to the mouth of the bottle a reaction occurs explosively Clearly thehydrogen and oxygen gases have not escaped from the bottle Yet they didnot react noticeably until you supplied additional energy in the form of alighted splint The example shown in Figure 17-6 illustrates this same phe-nomenon The soap bubbles you see billowing from the bowl are filled withhydrogen When the lighted splint introduces additional energy an explo-sive reaction occurs between the hydrogen that was contained in the bub-bles and oxygen in the air

As these examples show reaction spontaneity in the form of G impliesabsolutely nothing about the speed of the reaction G merely indicates thenatural tendency for a reaction or process to proceed Factors other thanspontaneity however do affect the rate of a chemical reaction These factorsare keys in controlling and using the power of chemistry

Vocabulary catalystinhibitorheterogeneous catalysthomogeneous catalyst

According to the collision theory chemical reactions occur when moleculescollide in a particular orientation and with sufficient energy to achieve acti-vation energy You can probably identify chemical reactions that occur fastsuch as gasoline combustion and others that occur more slowly such as ironrusting But can the reaction rate of any single reaction vary or is the reac-tion rate constant regardless of the conditions In this section you will learnthat the reaction rate for almost any chemical reaction can be modified byvarying the conditions of the reaction

The Nature of ReactantsAn important factor that affects the rate of a chemical reaction is the reactivenature of the reactants As you know some substances react more readily thanothers For example calcium and sodium are both reactive metals howeverwhat happens when each metal is added to water is distinctly different Whena small piece of calcium is placed in cold water as shown in Figure 17-7athe calcium and water react slowly to form hydrogen gas and aqueous calci-um hydroxide

Ca(s) 2H2O(l) 0 H2(g) Ca(OH)2(aq)

When a small piece of sodium is placed in cold water the sodium and waterreact quickly to form hydrogen gas and aqueous sodium hydroxide as shownin Figure 17-7b

2Na(s) 2H2O(l) 0 H2(g) 2NaOH(aq)

Comparing the two equations itrsquos evident that the reactions are similarHowever the reaction between sodium and water occurs much fasterbecause sodium is more reactive with water than calcium is In fact the reac-tion releases so much heat so quickly that the hydrogen gas ignites as it isformed

ConcentrationReactions speed up when the concentrations of reacting particles areincreased One of the fundamental principles of the collision theory is thatparticles must collide to react The number of particles in a reaction makes adifference in the rate at which the reaction takes place Think about a reac-tion where reactant A combines with reactant B At a given concentration ofA and B the molecules of A collide with B to produce AB at a particular rateWhat happens if the amount of B is increased Increasing the concentrationof B makes more molecules available with which A can collide Reactant Aldquofindsrdquo reactant B more easily because there are more B molecules in thearea which increases probability of collision and ultimately increases therate of reaction between A and B

Look at the two reactions shown in Figure 17-8 Steel wool is first heat-ed over a burner until it is red hot In Figure 17-8a the hot steel wool reactswith oxygen in the air How does this reaction compare with the one inFigure 17-8b in which the hot steel wool is lowered immediately into a flaskcontaining nearly 100 percent oxygenmdashapproximately five times the concen-tration of oxygen in air Applying the collision theory to this reaction thehigher concentration of oxygen increases the collision frequency betweeniron atoms and oxygen molecules which increases the rate of the reaction

If you have ever been near a person using bottled oxygen or seen an oxy-gen generator you may have noticed a sign cautioning against smoking orusing open flames Can you now explain the reason for the caution noticeThe high concentration of oxygen could cause a combustion reaction to occurat an explosive rate The CHEMLAB at the end of this chapter gives you anopportunity to further investigate the effect of concentration on reaction rates

Surface AreaNow suppose you were to lower a red-hot chunk of steel instead of steelwool into a flask of oxygen gas The oxygen would react with the steel muchmore slowly than it would with the steel wool Using what you know aboutthe collision theory can you explain why You are correct if you said thatfor the same mass of iron steel wool has much more surface area than thechunk of steel The greater surface area of the steel wool allows the oxygenmolecules to collide with many more iron atoms per unit of time

172 Factors Affecting Reaction Rates 537

Figure 17-8

The concentration of oxygenin the air surrounding the steelwool is much less than that ofthe pure oxygen in the flask

The higher oxygen concen-tration accounts for the fasterreaction

Pulverizing (or grinding) a substance is one way to increase its rate ofreaction This is because for the same mass many small particles possessmore total surface area than one large particle So a spoonful of granulatedsugar placed in a cup of water dissolves faster than the same mass of sugarin a single chunk which has less surface area as shown in Figure 17-9 Thisexample illustrates that increasing the surface area of a reactant does notchange its concentration but it does increase the rate of reaction by increas-ing the collision rate between reacting particles

TemperatureGenerally increasing the temperature at which a reaction occurs increasesthe reaction rate For example you know that the reactions that cause foodsto spoil occur much faster at room temperature than when the foods arerefrigerated The graph in Figure 17-10a illustrates that increasing the tem-perature by 10 K can approximately double the rate of a reaction How cana small increase in temperature have such a significant effect

As you learned in Chapter 13 increasing the temperature of a substanceincreases the average kinetic energy of the particles that make up the sub-stance For that reason reacting particles collide more frequently at highertemperatures than at lower temperatures However that fact alone doesnrsquotaccount for the increase in reaction rate with increasing temperature To bet-ter understand how reaction rate varies with temperature examine the graphshown in Figure 17-10b This graph compares the numbers of particles hav-ing sufficient energy to react at temperatures T1 and T2 where T2 is greaterthan T1 The shaded area under each curve represents the number of colli-sions having energy equal to or greater than the activation energy The dot-ted line indicates the activation energy (Ea) for the reaction How do theshaded areas compare The number of high-energy collisions at the highertemperature T2 is much greater than at the lower temperature T1 Thereforeas the temperature increases more collisions result in a reaction

As you can see increasing the temperature of the reactants increases thereaction rate because raising the kinetic energy of the reacting particles rais-es both the collision frequency and the collision energy You can investigatethe relationship between reaction rate and temperature by performing theminiLAB for this chapter

CatalystsYoursquove seen that increasing the temperature andor the concentration of reac-tants can dramatically increase the rate of a reaction However an increasein temperature is not always the best (or most practical) thing to do Forexample suppose that you want to increase the rate of a reaction such as thedecomposition of glucose in a living cell Increasing the temperature andorthe concentration of reactants is not a viable alternative because it mightharm or kill the cell

It is a fact that many chemical reactions in living organisms would notoccur quickly enough to sustain life at normal living temperatures if it werenot for the presence of enzymes An enzyme is a type of catalyst a sub-stance that increases the rate of a chemical reaction without itself being con-sumed in the reaction Although catalysts are important substances in achemical reaction a catalyst does not yield more product and is not includ-ed in the product(s) of the reaction In fact catalysts are not included in thechemical equation

Note that the activation energy for the catalyzed reaction is much lower thanfor the uncatalyzed reaction The lower activation energy for the catalyzedreaction means that more collisions have sufficient energy to initiate reac-tion It might help you to visualize this relationship by thinking of the reac-tionrsquos activation energy as a mountain range to be crossed as shown inFigure 17-12 In this analogy the tunnel representing the catalyzed path-way provides an easier and therefore quicker route to the other side of themountains

Another type of substance that affects reaction rates is called an inhibitorUnlike a catalyst which speeds up reaction rates an inhibitor is a substancethat slows down or inhibits reaction rates Some inhibitors in fact actuallyprevent a reaction from happening at all

In our fast-paced world it might seem unlikely that it would be desirableto slow a reaction But if you think about your environment you can proba-bly come up with several uses for inhibitors One of the primary applicationsfor inhibitors is in the food industry where inhibitors are called preserva-tives Figure 17-13 shows how a commercially available fruit freshener

Objectivesbull Express the relationship

between reaction rate andconcentration

bull Determine reaction ordersusing the method of initialrates

Vocabulary rate lawspecific rate constantreaction ordermethod of initial rates

In Section 171 you learned how to calculate the average rate of a chemicalreaction given the initial and final times and concentrations The word aver-age is important because most chemical reactions slow down as the reactantsare consumed To understand why most reaction rates slow over time recallthat the collision theory states that chemical reactions can occur only whenthe reacting particles collide and that reaction rate depends upon reactantconcentration As reactants are consumed fewer particles collide and thereaction slows Chemists use the concept of rate laws to quantify the resultsof the collision theory in terms of a mathematical relationship between therate of a chemical reaction and the reactant concentration

Reaction Rate LawsThe equation that expresses the mathematical relationship between the rateof a chemical reaction and the concentration of reactants is called a rate lawFor example the reaction A 0 B which is a one-step reaction has only oneactivated complex between reactants and products The rate law for this reac-tion is expressed as

where k is the specific rate constant or a numerical value that relates reac-tion rate and concentration of reactants at a given temperature Units for therate constant include L(mols) L2(mol2s) and sndash1 Depending on the reac-tion conditions especially temperature k is unique for every reaction

The rate law means that the reaction rate is directly proportional to the molarconcentration of A Thus doubling the concentration of A will double the reac-tion rate Increasing the concentration of A by a factor of 5 will increase thereaction rate by a factor of 5 The specific rate constant k does not change withconcentration however k does change with temperature A large value of kmeans that A reacts rapidly to form B What does a small value of k mean

Rate k[A]

Reaction order In the expression Rate k[A] it is understood that thenotation [A] means the same as [A]1 In other words for reactant A theunderstood exponent 1 is called the reaction order The reaction order for areactant defines how the rate is affected by the concentration of that reactantFor example the rate law for the decomposition of H2O2 is expressed by thefollowing equation

Rate k[H2O2]

Because the reaction rate is directly proportional to the concentration ofH2O2 raised to the first power [H2O2]

1 the decomposition of H2O2 is said tobe first order in H2O2 Because the reaction is first order in H2O2 the reac-tion rate changes in the same proportion that the concentration of H2O2changes So if the H2O2 concentration decreases to one-half its originalvalue the reaction rate is halved as well

Recall from Section 171 that reaction rates are determined from experi-mental data Because reaction order is based on reaction rates it follows thatreaction order also is determined experimentally Finally because the rateconstant describes the reaction rate k too must be determined experimen-tally Figure 17-14 illustrates two of several experimental methods that arecommonly used to measure reaction rates

Other reaction orders The overall reaction order of a chemical reactionis the sum of the orders for the individual reactants in the rate law Manychemical reactions particularly those having more than one reactant are notfirst order Consider the general form for a chemical reaction with two reac-tants In this chemical equation a and b are coefficients

aA bB 0 products

The general rate law for such a reaction is

Rate k[A]m[B]n

where m and n are the reaction orders for A and B respectively Only if thereaction between A and B occurs in a single step (and with a single activat-ed complex) does m a and n b Thatrsquos unlikely however because sin-gle-step reactions are uncommon

Determining Reaction OrderOne common experimental method of evaluating reaction order is called themethod of initial rates The method of initial rates determines reactionorder by comparing the initial rates of a reaction carried out with varyingreactant concentrations To understand how this method works letrsquos use thegeneral reaction aA bB 0 products Suppose that this reaction is carriedout with varying concentrations of A and B and yields the initial reactionrates shown in Table 17-3

Recall that the general rate law for this type of reaction is

Rate k[A]m[B]n

To determine m the concentrations and reaction rates in Trials 1 and 2 arecompared As you can see from the data while the concentration of Bremains constant the concentration of A in Trial 2 is twice that of Trial 1Note that the initial rate in Trial 2 is twice that of Trial 1 Because doubling[A] doubles the rate the reaction must be first order in A That is because2m 2 m must equal 1 The same method is used to determine n only thistime Trials 2 and 3 are compared Doubling the concentration of B causes therate to increase by four times Because 2n 4 n must equal 2 This infor-mation suggests that the reaction is second order in B giving the followingoverall rate law

Rate k[A]1[B]2

The overall reaction order is third order (sum of exponents 2 1 3)

Instantaneous Reaction Ratesand Reaction Mechanisms

Vocabularyinstantaneous ratecomplex reactionreaction mechanismintermediaterate-determining step

The average reaction rate you learned to calculate in Section 173 givesimportant information about the reaction over a period of time Howeverchemists also may need to know at what rate the reaction is proceeding at aspecific time A pharmacist developing a new drug treatment might need toknow the progress of a reaction at an exact instant This information makesit possible to adjust the product for maximum performance Can you think ofother situations where it might be critical to know the specific reaction rateat a given time

Instantaneous Reaction RatesThe decomposition of hydrogen peroxide (H2O2) is represented as follows

2H2O2(aq) 0 2H2O(l) O2(g)

For this reaction the decrease in H2O2 concentration over time is shown inFigure 17-15 The curved line shows how the reaction rate decreases as thereaction proceeds The instantaneous rate or the rate of decomposition ata specific time can be determined by finding the slope of the straight linetangent to the curve at that instant This is because the slope of the tangentto the curve at a particular point is [H2O2]t which is one way to expressthe reaction rate In other words the rate of change in H2O2 concentrationrelates to one specific point (or instant) on the graph

Another way to determine the instantaneous rate for a chemical reactionis to use the experimentally determined rate law given the reactant concen-trations and the specific rate constant for the temperature at which the reactionoccurs For example the decomposition of dinitrogen pentoxide (N2O5) intonitrogen dioxide (NO2) and oxygen (O2) is given by the following equation

2NO(g) H2(g) 0 N2O(g) H2O(g)

Calculate the instantaneous rate when the reactant concentrations are[NO] = 000200M and [H2] = 000400M

1 Analyze the ProblemThe rate law can be expressed by Rate k[NO]2[H2] Therefore the instantaneous reaction rate can be determined by insertingreactant concentrations and the specific rate constant into therate law equation

Known Unknown

[NO] 000200M Rate mol(Lmiddots)[H2] 000400Mk 290 102 (L2(mol2middots))

2 Solve for the UnknownInsert the known quantities into the rate law equation

Rate k[NO]2[H2]

Rate 290 102 (L2(mol2middots)(000200 molL)2(000400 molL))

Rate 464 106 mol(Lmiddots)

3 Evaluate the AnswerAre the units correct Units in the calculation cancel to give mol(Lmiddots)which is the common unit for the expression of reaction rates Is themagnitude reasonable A magnitude of approximately 106 mol(Lmiddots)fits with the quantities given and the rate law equation

PRACTICE PROBLEMSUse the rate law in Example Problem 17-2 and the concentrations given ineach practice problem to calculate the instantaneous rate for the reactionbetween NO and H2

In an automobile assemblyplant the process that is mosttime consuming limits the pro-duction rate For examplebecause it takes longer to installthe onboard computer systemthan it takes to attach the hoodassembly the computer installa-tion is a rate-determining step

Reaction MechanismsMost chemical reactions consist of a sequence of two or more simpler reac-tions For example recent evidence indicates that the reaction 2O3 0 3O2occurs in three steps after intense ultraviolet radiation from the sun liberateschlorine atoms from certain compounds in Earthrsquos stratosphere Steps 1 and2 in this reaction may occur simultaneously or in reverse order

1 Chlorine atoms decompose ozone according to the equation Cl O3 0 O2 ClO

2 Ultraviolet radiation causes the decomposition reaction O3 0 O2 O

3 ClO produced in the reaction in step 1 reacts with O produced in step 2according to the equation ClO O 0 Cl O2

Each of the reactions described in steps 1 through 3 is called an elementarystep These three elementary steps comprise the complex reaction 2O3 0 3O2A complex reaction is one that consists of two or more elementary steps Thecomplete sequence of elementary steps that make up a complex reaction iscalled a reaction mechanism Adding the elementary steps in steps 1 through3 and canceling formulas that occur in equal amounts on both sides of the reac-tion arrow produce the net equation for the complex reaction as shown below

Elementary step Cl O3 0 O2 ClO

Elementary step O3 0 O2 O

Elementary step ClO O 0 Cl O2

Complex reaction 2O3 0 3O2

Because chlorine atoms react in step 1 of the reaction mechanism and arere-formed in step 3 chlorine is said to catalyze the decomposition of ozoneDo you know why Because ClO and O are formed in the reactions in steps1 and 2 respectively and are consumed in the reaction in step 3 they arecalled intermediates In a complex reaction an intermediate is a substanceproduced in one elementary step and consumed in a subsequent elementarystep Catalysts and intermediates do not appear in the net chemical equation

Rate-determining step You have probably heard the expression ldquoAchain is no stronger than its weakest linkrdquo Chemical reactions too have aldquoweakest linkrdquo in that a complex reaction can proceed no faster than theslowest of its elementary steps In other words the slowest elementary stepin a reaction mechanism limits the instantaneous rate of the overall reaction

For that reason the slowest of the elementary steps in a complex reaction iscalled the rate-determining step Figure 17-16 illustrates this concept in amanufacturing plant

To see how the rate-determining step affects reaction rate again considerthe gas-phase reaction between hydrogen and nitrogen monoxide discussedearlier in the chapter

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

A proposed mechanism for this reaction consists of the following elementarysteps

2NO 0 N2O2 (fast)

N2O2 H2 0 N2O H2O (slow)

N2O H2 0 N2 H2O (fast)

Although the first and third elementary steps occur relatively fast the mid-dle step is the slowest and it limits the overall reaction rate It is the rate-determining step The relative energy levels of reactants intermediatesproducts and activated complex are illustrated in Figure 17-17

Chemists can make use of instantaneous reaction rates reaction ordersand rate-determining steps to develop efficient ways to manufacture prod-ucts such as pharmaceuticals By knowing which step of the reaction is slow-est a chemist can work to speed up that rate-determining step and therebyincrease the rate of the overall reaction

According to the collision theory chemical reactions occur when moleculescollide in a particular orientation and with sufficient energy to achieve acti-vation energy You can probably identify chemical reactions that occur fastsuch as gasoline combustion and others that occur more slowly such as ironrusting But can the reaction rate of any single reaction vary or is the reac-tion rate constant regardless of the conditions In this section you will learnthat the reaction rate for almost any chemical reaction can be modified byvarying the conditions of the reaction

The Nature of ReactantsAn important factor that affects the rate of a chemical reaction is the reactivenature of the reactants As you know some substances react more readily thanothers For example calcium and sodium are both reactive metals howeverwhat happens when each metal is added to water is distinctly different Whena small piece of calcium is placed in cold water as shown in Figure 17-7athe calcium and water react slowly to form hydrogen gas and aqueous calci-um hydroxide

Ca(s) 2H2O(l) 0 H2(g) Ca(OH)2(aq)

When a small piece of sodium is placed in cold water the sodium and waterreact quickly to form hydrogen gas and aqueous sodium hydroxide as shownin Figure 17-7b

2Na(s) 2H2O(l) 0 H2(g) 2NaOH(aq)

Comparing the two equations itrsquos evident that the reactions are similarHowever the reaction between sodium and water occurs much fasterbecause sodium is more reactive with water than calcium is In fact the reac-tion releases so much heat so quickly that the hydrogen gas ignites as it isformed

ConcentrationReactions speed up when the concentrations of reacting particles areincreased One of the fundamental principles of the collision theory is thatparticles must collide to react The number of particles in a reaction makes adifference in the rate at which the reaction takes place Think about a reac-tion where reactant A combines with reactant B At a given concentration ofA and B the molecules of A collide with B to produce AB at a particular rateWhat happens if the amount of B is increased Increasing the concentrationof B makes more molecules available with which A can collide Reactant Aldquofindsrdquo reactant B more easily because there are more B molecules in thearea which increases probability of collision and ultimately increases therate of reaction between A and B

Look at the two reactions shown in Figure 17-8 Steel wool is first heat-ed over a burner until it is red hot In Figure 17-8a the hot steel wool reactswith oxygen in the air How does this reaction compare with the one inFigure 17-8b in which the hot steel wool is lowered immediately into a flaskcontaining nearly 100 percent oxygenmdashapproximately five times the concen-tration of oxygen in air Applying the collision theory to this reaction thehigher concentration of oxygen increases the collision frequency betweeniron atoms and oxygen molecules which increases the rate of the reaction

If you have ever been near a person using bottled oxygen or seen an oxy-gen generator you may have noticed a sign cautioning against smoking orusing open flames Can you now explain the reason for the caution noticeThe high concentration of oxygen could cause a combustion reaction to occurat an explosive rate The CHEMLAB at the end of this chapter gives you anopportunity to further investigate the effect of concentration on reaction rates

Surface AreaNow suppose you were to lower a red-hot chunk of steel instead of steelwool into a flask of oxygen gas The oxygen would react with the steel muchmore slowly than it would with the steel wool Using what you know aboutthe collision theory can you explain why You are correct if you said thatfor the same mass of iron steel wool has much more surface area than thechunk of steel The greater surface area of the steel wool allows the oxygenmolecules to collide with many more iron atoms per unit of time

Figure 17-8

The concentration of oxygenin the air surrounding the steelwool is much less than that ofthe pure oxygen in the flask

The higher oxygen concen-tration accounts for the fasterreaction

Pulverizing (or grinding) a substance is one way to increase its rate ofreaction This is because for the same mass many small particles possessmore total surface area than one large particle So a spoonful of granulatedsugar placed in a cup of water dissolves faster than the same mass of sugarin a single chunk which has less surface area as shown in Figure 17-9 Thisexample illustrates that increasing the surface area of a reactant does notchange its concentration but it does increase the rate of reaction by increas-ing the collision rate between reacting particles

TemperatureGenerally increasing the temperature at which a reaction occurs increasesthe reaction rate For example you know that the reactions that cause foodsto spoil occur much faster at room temperature than when the foods arerefrigerated The graph in Figure 17-10a illustrates that increasing the tem-perature by 10 K can approximately double the rate of a reaction How cana small increase in temperature have such a significant effect

As you learned in Chapter 13 increasing the temperature of a substanceincreases the average kinetic energy of the particles that make up the sub-stance For that reason reacting particles collide more frequently at highertemperatures than at lower temperatures However that fact alone doesnrsquotaccount for the increase in reaction rate with increasing temperature To bet-ter understand how reaction rate varies with temperature examine the graphshown in Figure 17-10b This graph compares the numbers of particles hav-ing sufficient energy to react at temperatures T1 and T2 where T2 is greaterthan T1 The shaded area under each curve represents the number of colli-sions having energy equal to or greater than the activation energy The dot-ted line indicates the activation energy (Ea) for the reaction How do theshaded areas compare The number of high-energy collisions at the highertemperature T2 is much greater than at the lower temperature T1 Thereforeas the temperature increases more collisions result in a reaction

As you can see increasing the temperature of the reactants increases thereaction rate because raising the kinetic energy of the reacting particles rais-es both the collision frequency and the collision energy You can investigatethe relationship between reaction rate and temperature by performing theminiLAB for this chapter

CatalystsYoursquove seen that increasing the temperature andor the concentration of reac-tants can dramatically increase the rate of a reaction However an increasein temperature is not always the best (or most practical) thing to do Forexample suppose that you want to increase the rate of a reaction such as thedecomposition of glucose in a living cell Increasing the temperature andorthe concentration of reactants is not a viable alternative because it mightharm or kill the cell

It is a fact that many chemical reactions in living organisms would notoccur quickly enough to sustain life at normal living temperatures if it werenot for the presence of enzymes An enzyme is a type of catalyst a sub-stance that increases the rate of a chemical reaction without itself being con-sumed in the reaction Although catalysts are important substances in achemical reaction a catalyst does not yield more product and is not includ-ed in the product(s) of the reaction In fact catalysts are not included in thechemical equation

Compare the amount of time itwould take this train to travelover or around the barrier withthe time it takes to travelthrough the barrier Obviouslytravel is faster through themountain with the aid of thetunnel

Note that the activation energy for the catalyzed reaction is much lower thanfor the uncatalyzed reaction The lower activation energy for the catalyzedreaction means that more collisions have sufficient energy to initiate reac-tion It might help you to visualize this relationship by thinking of the reac-tionrsquos activation energy as a mountain range to be crossed as shown inFigure 17-12 In this analogy the tunnel representing the catalyzed path-way provides an easier and therefore quicker route to the other side of themountains

Another type of substance that affects reaction rates is called an inhibitorUnlike a catalyst which speeds up reaction rates an inhibitor is a substancethat slows down or inhibits reaction rates Some inhibitors in fact actuallyprevent a reaction from happening at all

In our fast-paced world it might seem unlikely that it would be desirableto slow a reaction But if you think about your environment you can proba-bly come up with several uses for inhibitors One of the primary applicationsfor inhibitors is in the food industry where inhibitors are called preserva-tives Figure 17-13 shows how a commercially available fruit freshener

Heterogeneous and homogeneous catalysts In order to reduce harm-ful engine emissions automobiles manufactured today must have catalyticconverters similar to the one described in How It Works at the end of thechapter The most effective catalysts for this application are transition metaloxides and metals such as palladium and platinum These substances catalyzereactions that convert nitrogen monoxide to nitrogen and oxygen carbonmonoxide to carbon dioxide and unburned gasoline to carbon dioxide andwater Because the catalysts in a catalytic converter are solids and the reac-tions they catalyze are gaseous the catalysts are called heterogeneous cata-lysts A heterogeneous catalyst exists in a physical state different than thatof the reaction it catalyzes A catalyst that exists in the same physical state asthe reaction it catalyzes is called a homogeneous catalyst For example ifboth an enzyme and the reaction it catalyzes are in aqueous solution theenzyme is a homogeneous catalyst

Section 173 Reaction Rate Laws

Objectivesbull Express the relationship

between reaction rate andconcentration

bull Determine reaction ordersusing the method of initialrates

Vocabulary rate lawspecific rate constantreaction ordermethod of initial rates

In Section 171 you learned how to calculate the average rate of a chemicalreaction given the initial and final times and concentrations The word aver-age is important because most chemical reactions slow down as the reactantsare consumed To understand why most reaction rates slow over time recallthat the collision theory states that chemical reactions can occur only whenthe reacting particles collide and that reaction rate depends upon reactantconcentration As reactants are consumed fewer particles collide and thereaction slows Chemists use the concept of rate laws to quantify the resultsof the collision theory in terms of a mathematical relationship between therate of a chemical reaction and the reactant concentration

Reaction Rate LawsThe equation that expresses the mathematical relationship between the rateof a chemical reaction and the concentration of reactants is called a rate lawFor example the reaction A 0 B which is a one-step reaction has only oneactivated complex between reactants and products The rate law for this reac-tion is expressed as

where k is the specific rate constant or a numerical value that relates reac-tion rate and concentration of reactants at a given temperature Units for therate constant include L(mols) L2(mol2s) and sndash1 Depending on the reac-tion conditions especially temperature k is unique for every reaction

The rate law means that the reaction rate is directly proportional to the molarconcentration of A Thus doubling the concentration of A will double the reac-tion rate Increasing the concentration of A by a factor of 5 will increase thereaction rate by a factor of 5 The specific rate constant k does not change withconcentration however k does change with temperature A large value of kmeans that A reacts rapidly to form B What does a small value of k mean

Reaction order In the expression Rate k[A] it is understood that thenotation [A] means the same as [A]1 In other words for reactant A theunderstood exponent 1 is called the reaction order The reaction order for areactant defines how the rate is affected by the concentration of that reactantFor example the rate law for the decomposition of H2O2 is expressed by thefollowing equation

Rate k[H2O2]

Because the reaction rate is directly proportional to the concentration ofH2O2 raised to the first power [H2O2]

1 the decomposition of H2O2 is said tobe first order in H2O2 Because the reaction is first order in H2O2 the reac-tion rate changes in the same proportion that the concentration of H2O2changes So if the H2O2 concentration decreases to one-half its originalvalue the reaction rate is halved as well

Recall from Section 171 that reaction rates are determined from experi-mental data Because reaction order is based on reaction rates it follows thatreaction order also is determined experimentally Finally because the rateconstant describes the reaction rate k too must be determined experimen-tally Figure 17-14 illustrates two of several experimental methods that arecommonly used to measure reaction rates

Other reaction orders The overall reaction order of a chemical reactionis the sum of the orders for the individual reactants in the rate law Manychemical reactions particularly those having more than one reactant are notfirst order Consider the general form for a chemical reaction with two reac-tants In this chemical equation a and b are coefficients

aA bB 0 products

The general rate law for such a reaction is

Rate k[A]m[B]n

where m and n are the reaction orders for A and B respectively Only if thereaction between A and B occurs in a single step (and with a single activat-ed complex) does m a and n b Thatrsquos unlikely however because sin-gle-step reactions are uncommon

For example the reaction between nitrogen monoxide (NO) and hydrogen(H2) is described by the following equation

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

This reaction which occurs in more than one step has the following rate law

Rate k[NO]2[H2]

This rate law was determined experimentally The data tell that the ratedepends on the concentration of the reactants as follows If [NO] doubles therate quadruples if [H2] doubles the rate doubles The reaction is describedas second order in NO first order in H2 and third order overall because thesum of the orders for the individual reactants (the sum of the exponents) is(2 1) or 3

Determining Reaction OrderOne common experimental method of evaluating reaction order is called themethod of initial rates The method of initial rates determines reactionorder by comparing the initial rates of a reaction carried out with varyingreactant concentrations To understand how this method works letrsquos use thegeneral reaction aA bB 0 products Suppose that this reaction is carriedout with varying concentrations of A and B and yields the initial reactionrates shown in Table 17-3

Recall that the general rate law for this type of reaction is

Rate k[A]m[B]n

To determine m the concentrations and reaction rates in Trials 1 and 2 arecompared As you can see from the data while the concentration of Bremains constant the concentration of A in Trial 2 is twice that of Trial 1Note that the initial rate in Trial 2 is twice that of Trial 1 Because doubling[A] doubles the rate the reaction must be first order in A That is because2m 2 m must equal 1 The same method is used to determine n only thistime Trials 2 and 3 are compared Doubling the concentration of B causes therate to increase by four times Because 2n 4 n must equal 2 This infor-mation suggests that the reaction is second order in B giving the followingoverall rate law

Rate k[A]1[B]2

The overall reaction order is third order (sum of exponents 2 1 3)

The average reaction rate you learned to calculate in Section 173 givesimportant information about the reaction over a period of time Howeverchemists also may need to know at what rate the reaction is proceeding at aspecific time A pharmacist developing a new drug treatment might need toknow the progress of a reaction at an exact instant This information makesit possible to adjust the product for maximum performance Can you think ofother situations where it might be critical to know the specific reaction rateat a given time

Instantaneous Reaction RatesThe decomposition of hydrogen peroxide (H2O2) is represented as follows

2H2O2(aq) 0 2H2O(l) O2(g)

For this reaction the decrease in H2O2 concentration over time is shown inFigure 17-15 The curved line shows how the reaction rate decreases as thereaction proceeds The instantaneous rate or the rate of decomposition ata specific time can be determined by finding the slope of the straight linetangent to the curve at that instant This is because the slope of the tangentto the curve at a particular point is [H2O2]t which is one way to expressthe reaction rate In other words the rate of change in H2O2 concentrationrelates to one specific point (or instant) on the graph

Another way to determine the instantaneous rate for a chemical reactionis to use the experimentally determined rate law given the reactant concen-trations and the specific rate constant for the temperature at which the reactionoccurs For example the decomposition of dinitrogen pentoxide (N2O5) intonitrogen dioxide (NO2) and oxygen (O2) is given by the following equation

2 Ultraviolet radiation causes the decomposition reaction O3 0 O2 O

3 ClO produced in the reaction in step 1 reacts with O produced in step 2according to the equation ClO O 0 Cl O2

Each of the reactions described in steps 1 through 3 is called an elementarystep These three elementary steps comprise the complex reaction 2O3 0 3O2A complex reaction is one that consists of two or more elementary steps Thecomplete sequence of elementary steps that make up a complex reaction iscalled a reaction mechanism Adding the elementary steps in steps 1 through3 and canceling formulas that occur in equal amounts on both sides of the reac-tion arrow produce the net equation for the complex reaction as shown below

Elementary step Cl O3 0 O2 ClO

Elementary step ClO O 0 Cl O2

Complex reaction 2O3 0 3O2

Because chlorine atoms react in step 1 of the reaction mechanism and arere-formed in step 3 chlorine is said to catalyze the decomposition of ozoneDo you know why Because ClO and O are formed in the reactions in steps1 and 2 respectively and are consumed in the reaction in step 3 they arecalled intermediates In a complex reaction an intermediate is a substanceproduced in one elementary step and consumed in a subsequent elementarystep Catalysts and intermediates do not appear in the net chemical equation

Rate-determining step You have probably heard the expression ldquoAchain is no stronger than its weakest linkrdquo Chemical reactions too have aldquoweakest linkrdquo in that a complex reaction can proceed no faster than theslowest of its elementary steps In other words the slowest elementary stepin a reaction mechanism limits the instantaneous rate of the overall reaction

For that reason the slowest of the elementary steps in a complex reaction iscalled the rate-determining step Figure 17-16 illustrates this concept in amanufacturing plant

N2O2 H2 0 N2O H2O (slow)

N2O H2 0 N2 H2O (fast)

Although the first and third elementary steps occur relatively fast the mid-dle step is the slowest and it limits the overall reaction rate It is the rate-determining step The relative energy levels of reactants intermediatesproducts and activated complex are illustrated in Figure 17-17

Chemists can make use of instantaneous reaction rates reaction ordersand rate-determining steps to develop efficient ways to manufacture prod-ucts such as pharmaceuticals By knowing which step of the reaction is slow-est a chemist can work to speed up that rate-determining step and therebyincrease the rate of the overall reaction

In many models of catalytic converters this inner structure resembles tubes in a honeycomb arrangement which provides significant surface area to accommodate the catalysts

At high temperatures (300ndash500C) on the platinum catalyst surface the dangerous carbon monoxide and hydrocarbons react with oxygen to form the compounds carbon dioxide and water

Inside the catalytic converter is a porous ceramic structure with a surface coating of platinum and rhodium particles

5 At the rhodium catalyst surface nitric oxide is converted to nitrogen and oxygen

Gasesfrom the engine and the air pass through the exhaust system to the catalytic converter Oxygen intake into the engine at this point is critical for the reactions of the catalysts

Catalytic ConverterConcerns for our environment have made a hugeimpact in the products and processes we use every dayThe catalytic converter is one of those impacts

When a combustion engine converts fuel into ener-gy the reactions of the combustion process are incom-plete Incomplete combustion results in the productionof poisonous carbon monoxide and undesirable nitro-gen oxides Since 1975 catalytic converters havereduced the exhaust emissions that contribute to airpollution by approximately 90

Key Equations and Relationships

Summary171 A Model for Reaction Ratesbull The rate of a chemical reaction is expressed as the

rate at which a reactant is consumed or the rate atwhich a product is formed

bull Reaction rates are generally calculated and expressedin moles per liter per second (mol(Lmiddots))

bull In order to react the particles in a chemical reactionmust collide in a correct orientation and with suffi-cient energy to form the activated complex

bull The rate of a chemical reaction is unrelated to thespontaneity of the reaction

172 Factors Affecting Reaction Ratesbull Key factors that influence the rate of chemical reac-

tions include reactivity concentration surface areatemperature and catalysts

bull Catalysts increase the rates of chemical reactions bylowering activation energies

bull Raising the temperature of a reaction increases therate of the reaction by increasing the collision fre-quency and the number of collisions forming theactivated complex

173 Reaction Rate Lawsbull The mathematical relationship between the rate of a

chemical reaction at a given temperature and theconcentrations of reactants is called the rate law

bull The rate law for a chemical reaction is determinedexperimentally using the method of initial rates

174 Instantaneous Reaction Rates andReaction Mechanisms

bull The instantaneous rate for a chemical reaction iscalculated from the rate law the specific rate con-stant and the concentrations of all reactants

bull Most chemical reactions are complex reactions con-sisting of two or more elementary steps

bull A reaction mechanism is the complete sequence ofelementary steps that make up a complex reaction

bull For a complex reaction the rate-determining steplimits the instantaneous rate of the overall reaction

ConcentrationReactions speed up when the concentrations of reacting particles areincreased One of the fundamental principles of the collision theory is thatparticles must collide to react The number of particles in a reaction makes adifference in the rate at which the reaction takes place Think about a reac-tion where reactant A combines with reactant B At a given concentration ofA and B the molecules of A collide with B to produce AB at a particular rateWhat happens if the amount of B is increased Increasing the concentrationof B makes more molecules available with which A can collide Reactant Aldquofindsrdquo reactant B more easily because there are more B molecules in thearea which increases probability of collision and ultimately increases therate of reaction between A and B

Look at the two reactions shown in Figure 17-8 Steel wool is first heat-ed over a burner until it is red hot In Figure 17-8a the hot steel wool reactswith oxygen in the air How does this reaction compare with the one inFigure 17-8b in which the hot steel wool is lowered immediately into a flaskcontaining nearly 100 percent oxygenmdashapproximately five times the concen-tration of oxygen in air Applying the collision theory to this reaction thehigher concentration of oxygen increases the collision frequency betweeniron atoms and oxygen molecules which increases the rate of the reaction

If you have ever been near a person using bottled oxygen or seen an oxy-gen generator you may have noticed a sign cautioning against smoking orusing open flames Can you now explain the reason for the caution noticeThe high concentration of oxygen could cause a combustion reaction to occurat an explosive rate The CHEMLAB at the end of this chapter gives you anopportunity to further investigate the effect of concentration on reaction rates

Surface AreaNow suppose you were to lower a red-hot chunk of steel instead of steelwool into a flask of oxygen gas The oxygen would react with the steel muchmore slowly than it would with the steel wool Using what you know aboutthe collision theory can you explain why You are correct if you said thatfor the same mass of iron steel wool has much more surface area than thechunk of steel The greater surface area of the steel wool allows the oxygenmolecules to collide with many more iron atoms per unit of time

The concentration of oxygenin the air surrounding the steelwool is much less than that ofthe pure oxygen in the flask

Pulverizing (or grinding) a substance is one way to increase its rate ofreaction This is because for the same mass many small particles possessmore total surface area than one large particle So a spoonful of granulatedsugar placed in a cup of water dissolves faster than the same mass of sugarin a single chunk which has less surface area as shown in Figure 17-9 Thisexample illustrates that increasing the surface area of a reactant does notchange its concentration but it does increase the rate of reaction by increas-ing the collision rate between reacting particles

TemperatureGenerally increasing the temperature at which a reaction occurs increasesthe reaction rate For example you know that the reactions that cause foodsto spoil occur much faster at room temperature than when the foods arerefrigerated The graph in Figure 17-10a illustrates that increasing the tem-perature by 10 K can approximately double the rate of a reaction How cana small increase in temperature have such a significant effect

As you learned in Chapter 13 increasing the temperature of a substanceincreases the average kinetic energy of the particles that make up the sub-stance For that reason reacting particles collide more frequently at highertemperatures than at lower temperatures However that fact alone doesnrsquotaccount for the increase in reaction rate with increasing temperature To bet-ter understand how reaction rate varies with temperature examine the graphshown in Figure 17-10b This graph compares the numbers of particles hav-ing sufficient energy to react at temperatures T1 and T2 where T2 is greaterthan T1 The shaded area under each curve represents the number of colli-sions having energy equal to or greater than the activation energy The dot-ted line indicates the activation energy (Ea) for the reaction How do theshaded areas compare The number of high-energy collisions at the highertemperature T2 is much greater than at the lower temperature T1 Thereforeas the temperature increases more collisions result in a reaction

As you can see increasing the temperature of the reactants increases thereaction rate because raising the kinetic energy of the reacting particles rais-es both the collision frequency and the collision energy You can investigatethe relationship between reaction rate and temperature by performing theminiLAB for this chapter

CatalystsYoursquove seen that increasing the temperature andor the concentration of reac-tants can dramatically increase the rate of a reaction However an increasein temperature is not always the best (or most practical) thing to do Forexample suppose that you want to increase the rate of a reaction such as thedecomposition of glucose in a living cell Increasing the temperature andorthe concentration of reactants is not a viable alternative because it mightharm or kill the cell

It is a fact that many chemical reactions in living organisms would notoccur quickly enough to sustain life at normal living temperatures if it werenot for the presence of enzymes An enzyme is a type of catalyst a sub-stance that increases the rate of a chemical reaction without itself being con-sumed in the reaction Although catalysts are important substances in achemical reaction a catalyst does not yield more product and is not includ-ed in the product(s) of the reaction In fact catalysts are not included in thechemical equation

Note that the activation energy for the catalyzed reaction is much lower thanfor the uncatalyzed reaction The lower activation energy for the catalyzedreaction means that more collisions have sufficient energy to initiate reac-tion It might help you to visualize this relationship by thinking of the reac-tionrsquos activation energy as a mountain range to be crossed as shown inFigure 17-12 In this analogy the tunnel representing the catalyzed path-way provides an easier and therefore quicker route to the other side of themountains

Another type of substance that affects reaction rates is called an inhibitorUnlike a catalyst which speeds up reaction rates an inhibitor is a substancethat slows down or inhibits reaction rates Some inhibitors in fact actuallyprevent a reaction from happening at all

In our fast-paced world it might seem unlikely that it would be desirableto slow a reaction But if you think about your environment you can proba-bly come up with several uses for inhibitors One of the primary applicationsfor inhibitors is in the food industry where inhibitors are called preserva-tives Figure 17-13 shows how a commercially available fruit freshener

Vocabulary rate lawspecific rate constantreaction ordermethod of initial rates

In Section 171 you learned how to calculate the average rate of a chemicalreaction given the initial and final times and concentrations The word aver-age is important because most chemical reactions slow down as the reactantsare consumed To understand why most reaction rates slow over time recallthat the collision theory states that chemical reactions can occur only whenthe reacting particles collide and that reaction rate depends upon reactantconcentration As reactants are consumed fewer particles collide and thereaction slows Chemists use the concept of rate laws to quantify the resultsof the collision theory in terms of a mathematical relationship between therate of a chemical reaction and the reactant concentration

Reaction Rate LawsThe equation that expresses the mathematical relationship between the rateof a chemical reaction and the concentration of reactants is called a rate lawFor example the reaction A 0 B which is a one-step reaction has only oneactivated complex between reactants and products The rate law for this reac-tion is expressed as

where k is the specific rate constant or a numerical value that relates reac-tion rate and concentration of reactants at a given temperature Units for therate constant include L(mols) L2(mol2s) and sndash1 Depending on the reac-tion conditions especially temperature k is unique for every reaction

The rate law means that the reaction rate is directly proportional to the molarconcentration of A Thus doubling the concentration of A will double the reac-tion rate Increasing the concentration of A by a factor of 5 will increase thereaction rate by a factor of 5 The specific rate constant k does not change withconcentration however k does change with temperature A large value of kmeans that A reacts rapidly to form B What does a small value of k mean

Reaction order In the expression Rate k[A] it is understood that thenotation [A] means the same as [A]1 In other words for reactant A theunderstood exponent 1 is called the reaction order The reaction order for areactant defines how the rate is affected by the concentration of that reactantFor example the rate law for the decomposition of H2O2 is expressed by thefollowing equation

Rate k[H2O2]

Because the reaction rate is directly proportional to the concentration ofH2O2 raised to the first power [H2O2]

1 the decomposition of H2O2 is said tobe first order in H2O2 Because the reaction is first order in H2O2 the reac-tion rate changes in the same proportion that the concentration of H2O2changes So if the H2O2 concentration decreases to one-half its originalvalue the reaction rate is halved as well

Recall from Section 171 that reaction rates are determined from experi-mental data Because reaction order is based on reaction rates it follows thatreaction order also is determined experimentally Finally because the rateconstant describes the reaction rate k too must be determined experimen-tally Figure 17-14 illustrates two of several experimental methods that arecommonly used to measure reaction rates

Other reaction orders The overall reaction order of a chemical reactionis the sum of the orders for the individual reactants in the rate law Manychemical reactions particularly those having more than one reactant are notfirst order Consider the general form for a chemical reaction with two reac-tants In this chemical equation a and b are coefficients

aA bB 0 products

The general rate law for such a reaction is

Rate k[A]m[B]n

where m and n are the reaction orders for A and B respectively Only if thereaction between A and B occurs in a single step (and with a single activat-ed complex) does m a and n b Thatrsquos unlikely however because sin-gle-step reactions are uncommon

For example the reaction between nitrogen monoxide (NO) and hydrogen(H2) is described by the following equation

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

This reaction which occurs in more than one step has the following rate law

Rate k[NO]2[H2]

This rate law was determined experimentally The data tell that the ratedepends on the concentration of the reactants as follows If [NO] doubles therate quadruples if [H2] doubles the rate doubles The reaction is describedas second order in NO first order in H2 and third order overall because thesum of the orders for the individual reactants (the sum of the exponents) is(2 1) or 3

Determining Reaction OrderOne common experimental method of evaluating reaction order is called themethod of initial rates The method of initial rates determines reactionorder by comparing the initial rates of a reaction carried out with varyingreactant concentrations To understand how this method works letrsquos use thegeneral reaction aA bB 0 products Suppose that this reaction is carriedout with varying concentrations of A and B and yields the initial reactionrates shown in Table 17-3

Recall that the general rate law for this type of reaction is

Rate k[A]m[B]n

To determine m the concentrations and reaction rates in Trials 1 and 2 arecompared As you can see from the data while the concentration of Bremains constant the concentration of A in Trial 2 is twice that of Trial 1Note that the initial rate in Trial 2 is twice that of Trial 1 Because doubling[A] doubles the rate the reaction must be first order in A That is because2m 2 m must equal 1 The same method is used to determine n only thistime Trials 2 and 3 are compared Doubling the concentration of B causes therate to increase by four times Because 2n 4 n must equal 2 This infor-mation suggests that the reaction is second order in B giving the followingoverall rate law

Rate k[A]1[B]2

The overall reaction order is third order (sum of exponents 2 1 3)

Instantaneous Reaction Ratesand Reaction Mechanisms

Objectivesbull Calculate instantaneous

The average reaction rate you learned to calculate in Section 173 givesimportant information about the reaction over a period of time Howeverchemists also may need to know at what rate the reaction is proceeding at aspecific time A pharmacist developing a new drug treatment might need toknow the progress of a reaction at an exact instant This information makesit possible to adjust the product for maximum performance Can you think ofother situations where it might be critical to know the specific reaction rateat a given time

Instantaneous Reaction RatesThe decomposition of hydrogen peroxide (H2O2) is represented as follows

2H2O2(aq) 0 2H2O(l) O2(g)

For this reaction the decrease in H2O2 concentration over time is shown inFigure 17-15 The curved line shows how the reaction rate decreases as thereaction proceeds The instantaneous rate or the rate of decomposition ata specific time can be determined by finding the slope of the straight linetangent to the curve at that instant This is because the slope of the tangentto the curve at a particular point is [H2O2]t which is one way to expressthe reaction rate In other words the rate of change in H2O2 concentrationrelates to one specific point (or instant) on the graph

Another way to determine the instantaneous rate for a chemical reactionis to use the experimentally determined rate law given the reactant concen-trations and the specific rate constant for the temperature at which the reactionoccurs For example the decomposition of dinitrogen pentoxide (N2O5) intonitrogen dioxide (NO2) and oxygen (O2) is given by the following equation

EXAMPLE PROBLEM 17-2

Calculating Instantaneous Reaction RatesThe following equation is first order in H2 and second order in NO with arate constant of 290 102 (L2(mol2middots))

2NO(g) H2(g) 0 N2O(g) H2O(g)

Calculate the instantaneous rate when the reactant concentrations are[NO] = 000200M and [H2] = 000400M

1 Analyze the ProblemThe rate law can be expressed by Rate k[NO]2[H2] Therefore the instantaneous reaction rate can be determined by insertingreactant concentrations and the specific rate constant into therate law equation

Known Unknown

[NO] 000200M Rate mol(Lmiddots)[H2] 000400Mk 290 102 (L2(mol2middots))

2 Solve for the UnknownInsert the known quantities into the rate law equation

Rate k[NO]2[H2]

Rate 290 102 (L2(mol2middots)(000200 molL)2(000400 molL))

Rate 464 106 mol(Lmiddots)

3 Evaluate the AnswerAre the units correct Units in the calculation cancel to give mol(Lmiddots)which is the common unit for the expression of reaction rates Is themagnitude reasonable A magnitude of approximately 106 mol(Lmiddots)fits with the quantities given and the rate law equation

PRACTICE PROBLEMSUse the rate law in Example Problem 17-2 and the concentrations given ineach practice problem to calculate the instantaneous rate for the reactionbetween NO and H2

25 [NO] 00100M and [H2] 000125M

26 [NO] 000446M and [H2] 000282M

The experimentally determined rate law for this reaction is

Rate k[N2O5]

where k 10 105 s1 If [N2O5] 0350M the instantaneous reactionrate would be calculated as

In an automobile assemblyplant the process that is mosttime consuming limits the pro-duction rate For examplebecause it takes longer to installthe onboard computer systemthan it takes to attach the hoodassembly the computer installa-tion is a rate-determining step

Reaction MechanismsMost chemical reactions consist of a sequence of two or more simpler reac-tions For example recent evidence indicates that the reaction 2O3 0 3O2occurs in three steps after intense ultraviolet radiation from the sun liberateschlorine atoms from certain compounds in Earthrsquos stratosphere Steps 1 and2 in this reaction may occur simultaneously or in reverse order

1 Chlorine atoms decompose ozone according to the equation Cl O3 0 O2 ClO

2 Ultraviolet radiation causes the decomposition reaction O3 0 O2 O

3 ClO produced in the reaction in step 1 reacts with O produced in step 2according to the equation ClO O 0 Cl O2

Each of the reactions described in steps 1 through 3 is called an elementarystep These three elementary steps comprise the complex reaction 2O3 0 3O2A complex reaction is one that consists of two or more elementary steps Thecomplete sequence of elementary steps that make up a complex reaction iscalled a reaction mechanism Adding the elementary steps in steps 1 through3 and canceling formulas that occur in equal amounts on both sides of the reac-tion arrow produce the net equation for the complex reaction as shown below

Elementary step Cl O3 0 O2 ClO

Elementary step O3 0 O2 O

Elementary step ClO O 0 Cl O2

Complex reaction 2O3 0 3O2

Because chlorine atoms react in step 1 of the reaction mechanism and arere-formed in step 3 chlorine is said to catalyze the decomposition of ozoneDo you know why Because ClO and O are formed in the reactions in steps1 and 2 respectively and are consumed in the reaction in step 3 they arecalled intermediates In a complex reaction an intermediate is a substanceproduced in one elementary step and consumed in a subsequent elementarystep Catalysts and intermediates do not appear in the net chemical equation

Rate-determining step You have probably heard the expression ldquoAchain is no stronger than its weakest linkrdquo Chemical reactions too have aldquoweakest linkrdquo in that a complex reaction can proceed no faster than theslowest of its elementary steps In other words the slowest elementary stepin a reaction mechanism limits the instantaneous rate of the overall reaction

For that reason the slowest of the elementary steps in a complex reaction iscalled the rate-determining step Figure 17-16 illustrates this concept in amanufacturing plant

To see how the rate-determining step affects reaction rate again considerthe gas-phase reaction between hydrogen and nitrogen monoxide discussedearlier in the chapter

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

A proposed mechanism for this reaction consists of the following elementarysteps

2NO 0 N2O2 (fast)

N2O2 H2 0 N2O H2O (slow)

N2O H2 0 N2 H2O (fast)

Although the first and third elementary steps occur relatively fast the mid-dle step is the slowest and it limits the overall reaction rate It is the rate-determining step The relative energy levels of reactants intermediatesproducts and activated complex are illustrated in Figure 17-17

Chemists can make use of instantaneous reaction rates reaction ordersand rate-determining steps to develop efficient ways to manufacture prod-ucts such as pharmaceuticals By knowing which step of the reaction is slow-est a chemist can work to speed up that rate-determining step and therebyincrease the rate of the overall reaction

Pulverizing (or grinding) a substance is one way to increase its rate ofreaction This is because for the same mass many small particles possessmore total surface area than one large particle So a spoonful of granulatedsugar placed in a cup of water dissolves faster than the same mass of sugarin a single chunk which has less surface area as shown in Figure 17-9 Thisexample illustrates that increasing the surface area of a reactant does notchange its concentration but it does increase the rate of reaction by increas-ing the collision rate between reacting particles

TemperatureGenerally increasing the temperature at which a reaction occurs increasesthe reaction rate For example you know that the reactions that cause foodsto spoil occur much faster at room temperature than when the foods arerefrigerated The graph in Figure 17-10a illustrates that increasing the tem-perature by 10 K can approximately double the rate of a reaction How cana small increase in temperature have such a significant effect

As you learned in Chapter 13 increasing the temperature of a substanceincreases the average kinetic energy of the particles that make up the sub-stance For that reason reacting particles collide more frequently at highertemperatures than at lower temperatures However that fact alone doesnrsquotaccount for the increase in reaction rate with increasing temperature To bet-ter understand how reaction rate varies with temperature examine the graphshown in Figure 17-10b This graph compares the numbers of particles hav-ing sufficient energy to react at temperatures T1 and T2 where T2 is greaterthan T1 The shaded area under each curve represents the number of colli-sions having energy equal to or greater than the activation energy The dot-ted line indicates the activation energy (Ea) for the reaction How do theshaded areas compare The number of high-energy collisions at the highertemperature T2 is much greater than at the lower temperature T1 Thereforeas the temperature increases more collisions result in a reaction

As you can see increasing the temperature of the reactants increases thereaction rate because raising the kinetic energy of the reacting particles rais-es both the collision frequency and the collision energy You can investigatethe relationship between reaction rate and temperature by performing theminiLAB for this chapter

Increasing the temperatureof a reaction increases the fre-quency of collisions and there-fore the rate of reaction

Increasing the temperaturealso raises the kinetic energy ofthe particles thus more of thecollisions at high temperatureshave enough energy to over-come the activation energy barrier and react

CatalystsYoursquove seen that increasing the temperature andor the concentration of reac-tants can dramatically increase the rate of a reaction However an increasein temperature is not always the best (or most practical) thing to do Forexample suppose that you want to increase the rate of a reaction such as thedecomposition of glucose in a living cell Increasing the temperature andorthe concentration of reactants is not a viable alternative because it mightharm or kill the cell

It is a fact that many chemical reactions in living organisms would notoccur quickly enough to sustain life at normal living temperatures if it werenot for the presence of enzymes An enzyme is a type of catalyst a sub-stance that increases the rate of a chemical reaction without itself being con-sumed in the reaction Although catalysts are important substances in achemical reaction a catalyst does not yield more product and is not includ-ed in the product(s) of the reaction In fact catalysts are not included in thechemical equation

How does a catalyst increase the reaction rate Figure 17-11 on the nextpage shows the energy diagram for an exothermic chemical reaction The redline represents the uncatalyzed reaction pathwaymdashthe reaction pathway withno catalyst present The blue line represents the catalyzed reaction pathway

Materials small beaker thermometer hot plate250-mL beaker balance water effervescent(bicarbonate) tablet stopwatch or clock withsecond hand

Procedure1 Take a single effervescent tablet and break it

into four roughly equal pieces

2 Measure the mass of one piece of the tabletMeasure 50 mL of room-temperature water(approximately 20degC) into a small cup orbeaker Measure the temperature of the water

3 With a stopwatch ready add the piece oftablet to the water Record the amount oftime elapsed between when the tablet hits thewater and when you see that all of the pieceof tablet has dissolved in the water

4 Repeat steps 2 and 3 twice more except usewater temperatures of about 50degC and 65degCBe sure to raise the temperature gradually andmaintain the desired temperature (equilibrate)throughout the run

Analysis1 Calculate the reaction rate by finding the

masstime for each run

2 Graph the reaction rate (masstime) versustemperature for the runs

3 What is the relationship between reaction rateand temperature for this reaction

4 Using your graphed data predict the reactionrate for the reaction carried out at 40degC Heatand equilibrate the water to 40degC and use thelast piece of tablet to test your prediction

5 How did your prediction for the reaction rateat 40degC compare to the actual reaction rate

Compare the amount of time itwould take this train to travelover or around the barrier withthe time it takes to travelthrough the barrier Obviouslytravel is faster through themountain with the aid of thetunnel

Note that the activation energy for the catalyzed reaction is much lower thanfor the uncatalyzed reaction The lower activation energy for the catalyzedreaction means that more collisions have sufficient energy to initiate reac-tion It might help you to visualize this relationship by thinking of the reac-tionrsquos activation energy as a mountain range to be crossed as shown inFigure 17-12 In this analogy the tunnel representing the catalyzed path-way provides an easier and therefore quicker route to the other side of themountains

Another type of substance that affects reaction rates is called an inhibitorUnlike a catalyst which speeds up reaction rates an inhibitor is a substancethat slows down or inhibits reaction rates Some inhibitors in fact actuallyprevent a reaction from happening at all

In our fast-paced world it might seem unlikely that it would be desirableto slow a reaction But if you think about your environment you can proba-bly come up with several uses for inhibitors One of the primary applicationsfor inhibitors is in the food industry where inhibitors are called preserva-tives Figure 17-13 shows how a commercially available fruit freshener

Vocabulary rate lawspecific rate constantreaction ordermethod of initial rates

In Section 171 you learned how to calculate the average rate of a chemicalreaction given the initial and final times and concentrations The word aver-age is important because most chemical reactions slow down as the reactantsare consumed To understand why most reaction rates slow over time recallthat the collision theory states that chemical reactions can occur only whenthe reacting particles collide and that reaction rate depends upon reactantconcentration As reactants are consumed fewer particles collide and thereaction slows Chemists use the concept of rate laws to quantify the resultsof the collision theory in terms of a mathematical relationship between therate of a chemical reaction and the reactant concentration

Reaction Rate LawsThe equation that expresses the mathematical relationship between the rateof a chemical reaction and the concentration of reactants is called a rate lawFor example the reaction A 0 B which is a one-step reaction has only oneactivated complex between reactants and products The rate law for this reac-tion is expressed as

where k is the specific rate constant or a numerical value that relates reac-tion rate and concentration of reactants at a given temperature Units for therate constant include L(mols) L2(mol2s) and sndash1 Depending on the reac-tion conditions especially temperature k is unique for every reaction

The rate law means that the reaction rate is directly proportional to the molarconcentration of A Thus doubling the concentration of A will double the reac-tion rate Increasing the concentration of A by a factor of 5 will increase thereaction rate by a factor of 5 The specific rate constant k does not change withconcentration however k does change with temperature A large value of kmeans that A reacts rapidly to form B What does a small value of k mean

Reaction order In the expression Rate k[A] it is understood that thenotation [A] means the same as [A]1 In other words for reactant A theunderstood exponent 1 is called the reaction order The reaction order for areactant defines how the rate is affected by the concentration of that reactantFor example the rate law for the decomposition of H2O2 is expressed by thefollowing equation

Rate k[H2O2]

Because the reaction rate is directly proportional to the concentration ofH2O2 raised to the first power [H2O2]

1 the decomposition of H2O2 is said tobe first order in H2O2 Because the reaction is first order in H2O2 the reac-tion rate changes in the same proportion that the concentration of H2O2changes So if the H2O2 concentration decreases to one-half its originalvalue the reaction rate is halved as well

Recall from Section 171 that reaction rates are determined from experi-mental data Because reaction order is based on reaction rates it follows thatreaction order also is determined experimentally Finally because the rateconstant describes the reaction rate k too must be determined experimen-tally Figure 17-14 illustrates two of several experimental methods that arecommonly used to measure reaction rates

Other reaction orders The overall reaction order of a chemical reactionis the sum of the orders for the individual reactants in the rate law Manychemical reactions particularly those having more than one reactant are notfirst order Consider the general form for a chemical reaction with two reac-tants In this chemical equation a and b are coefficients

aA bB 0 products

The general rate law for such a reaction is

Rate k[A]m[B]n

where m and n are the reaction orders for A and B respectively Only if thereaction between A and B occurs in a single step (and with a single activat-ed complex) does m a and n b Thatrsquos unlikely however because sin-gle-step reactions are uncommon

For example the reaction between nitrogen monoxide (NO) and hydrogen(H2) is described by the following equation

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

This reaction which occurs in more than one step has the following rate law

Rate k[NO]2[H2]

This rate law was determined experimentally The data tell that the ratedepends on the concentration of the reactants as follows If [NO] doubles therate quadruples if [H2] doubles the rate doubles The reaction is describedas second order in NO first order in H2 and third order overall because thesum of the orders for the individual reactants (the sum of the exponents) is(2 1) or 3

Determining Reaction OrderOne common experimental method of evaluating reaction order is called themethod of initial rates The method of initial rates determines reactionorder by comparing the initial rates of a reaction carried out with varyingreactant concentrations To understand how this method works letrsquos use thegeneral reaction aA bB 0 products Suppose that this reaction is carriedout with varying concentrations of A and B and yields the initial reactionrates shown in Table 17-3

Recall that the general rate law for this type of reaction is

Rate k[A]m[B]n

To determine m the concentrations and reaction rates in Trials 1 and 2 arecompared As you can see from the data while the concentration of Bremains constant the concentration of A in Trial 2 is twice that of Trial 1Note that the initial rate in Trial 2 is twice that of Trial 1 Because doubling[A] doubles the rate the reaction must be first order in A That is because2m 2 m must equal 1 The same method is used to determine n only thistime Trials 2 and 3 are compared Doubling the concentration of B causes therate to increase by four times Because 2n 4 n must equal 2 This infor-mation suggests that the reaction is second order in B giving the followingoverall rate law

Rate k[A]1[B]2

The overall reaction order is third order (sum of exponents 2 1 3)

The average reaction rate you learned to calculate in Section 173 givesimportant information about the reaction over a period of time Howeverchemists also may need to know at what rate the reaction is proceeding at aspecific time A pharmacist developing a new drug treatment might need toknow the progress of a reaction at an exact instant This information makesit possible to adjust the product for maximum performance Can you think ofother situations where it might be critical to know the specific reaction rateat a given time

Instantaneous Reaction RatesThe decomposition of hydrogen peroxide (H2O2) is represented as follows

2H2O2(aq) 0 2H2O(l) O2(g)

For this reaction the decrease in H2O2 concentration over time is shown inFigure 17-15 The curved line shows how the reaction rate decreases as thereaction proceeds The instantaneous rate or the rate of decomposition ata specific time can be determined by finding the slope of the straight linetangent to the curve at that instant This is because the slope of the tangentto the curve at a particular point is [H2O2]t which is one way to expressthe reaction rate In other words the rate of change in H2O2 concentrationrelates to one specific point (or instant) on the graph

Another way to determine the instantaneous rate for a chemical reactionis to use the experimentally determined rate law given the reactant concen-trations and the specific rate constant for the temperature at which the reactionoccurs For example the decomposition of dinitrogen pentoxide (N2O5) intonitrogen dioxide (NO2) and oxygen (O2) is given by the following equation

2NO(g) H2(g) 0 N2O(g) H2O(g)

Calculate the instantaneous rate when the reactant concentrations are[NO] = 000200M and [H2] = 000400M

Reaction MechanismsMost chemical reactions consist of a sequence of two or more simpler reac-tions For example recent evidence indicates that the reaction 2O3 0 3O2occurs in three steps after intense ultraviolet radiation from the sun liberateschlorine atoms from certain compounds in Earthrsquos stratosphere Steps 1 and2 in this reaction may occur simultaneously or in reverse order

1 Chlorine atoms decompose ozone according to the equation Cl O3 0 O2 ClO

2 Ultraviolet radiation causes the decomposition reaction O3 0 O2 O

3 ClO produced in the reaction in step 1 reacts with O produced in step 2according to the equation ClO O 0 Cl O2

Each of the reactions described in steps 1 through 3 is called an elementarystep These three elementary steps comprise the complex reaction 2O3 0 3O2A complex reaction is one that consists of two or more elementary steps Thecomplete sequence of elementary steps that make up a complex reaction iscalled a reaction mechanism Adding the elementary steps in steps 1 through3 and canceling formulas that occur in equal amounts on both sides of the reac-tion arrow produce the net equation for the complex reaction as shown below

Elementary step Cl O3 0 O2 ClO

Elementary step O3 0 O2 O

Elementary step ClO O 0 Cl O2

Complex reaction 2O3 0 3O2

Because chlorine atoms react in step 1 of the reaction mechanism and arere-formed in step 3 chlorine is said to catalyze the decomposition of ozoneDo you know why Because ClO and O are formed in the reactions in steps1 and 2 respectively and are consumed in the reaction in step 3 they arecalled intermediates In a complex reaction an intermediate is a substanceproduced in one elementary step and consumed in a subsequent elementarystep Catalysts and intermediates do not appear in the net chemical equation

Rate-determining step You have probably heard the expression ldquoAchain is no stronger than its weakest linkrdquo Chemical reactions too have aldquoweakest linkrdquo in that a complex reaction can proceed no faster than theslowest of its elementary steps In other words the slowest elementary stepin a reaction mechanism limits the instantaneous rate of the overall reaction

For that reason the slowest of the elementary steps in a complex reaction iscalled the rate-determining step Figure 17-16 illustrates this concept in amanufacturing plant

To see how the rate-determining step affects reaction rate again considerthe gas-phase reaction between hydrogen and nitrogen monoxide discussedearlier in the chapter

2NO 0 N2O2 (fast)

N2O2 H2 0 N2O H2O (slow)

N2O H2 0 N2 H2O (fast)

Although the first and third elementary steps occur relatively fast the mid-dle step is the slowest and it limits the overall reaction rate It is the rate-determining step The relative energy levels of reactants intermediatesproducts and activated complex are illustrated in Figure 17-17

Chemists can make use of instantaneous reaction rates reaction ordersand rate-determining steps to develop efficient ways to manufacture prod-ucts such as pharmaceuticals By knowing which step of the reaction is slow-est a chemist can work to speed up that rate-determining step and therebyincrease the rate of the overall reaction

CatalystsYoursquove seen that increasing the temperature andor the concentration of reac-tants can dramatically increase the rate of a reaction However an increasein temperature is not always the best (or most practical) thing to do Forexample suppose that you want to increase the rate of a reaction such as thedecomposition of glucose in a living cell Increasing the temperature andorthe concentration of reactants is not a viable alternative because it mightharm or kill the cell

It is a fact that many chemical reactions in living organisms would notoccur quickly enough to sustain life at normal living temperatures if it werenot for the presence of enzymes An enzyme is a type of catalyst a sub-stance that increases the rate of a chemical reaction without itself being con-sumed in the reaction Although catalysts are important substances in achemical reaction a catalyst does not yield more product and is not includ-ed in the product(s) of the reaction In fact catalysts are not included in thechemical equation

Note that the activation energy for the catalyzed reaction is much lower thanfor the uncatalyzed reaction The lower activation energy for the catalyzedreaction means that more collisions have sufficient energy to initiate reac-tion It might help you to visualize this relationship by thinking of the reac-tionrsquos activation energy as a mountain range to be crossed as shown inFigure 17-12 In this analogy the tunnel representing the catalyzed path-way provides an easier and therefore quicker route to the other side of themountains

Another type of substance that affects reaction rates is called an inhibitorUnlike a catalyst which speeds up reaction rates an inhibitor is a substancethat slows down or inhibits reaction rates Some inhibitors in fact actuallyprevent a reaction from happening at all

In our fast-paced world it might seem unlikely that it would be desirableto slow a reaction But if you think about your environment you can proba-bly come up with several uses for inhibitors One of the primary applicationsfor inhibitors is in the food industry where inhibitors are called preserva-tives Figure 17-13 shows how a commercially available fruit freshener

Section 173 Reaction Rate Laws

Objectivesbull Express the relationship

between reaction rate andconcentration

bull Determine reaction ordersusing the method of initialrates

Vocabulary rate lawspecific rate constantreaction ordermethod of initial rates

In Section 171 you learned how to calculate the average rate of a chemicalreaction given the initial and final times and concentrations The word aver-age is important because most chemical reactions slow down as the reactantsare consumed To understand why most reaction rates slow over time recallthat the collision theory states that chemical reactions can occur only whenthe reacting particles collide and that reaction rate depends upon reactantconcentration As reactants are consumed fewer particles collide and thereaction slows Chemists use the concept of rate laws to quantify the resultsof the collision theory in terms of a mathematical relationship between therate of a chemical reaction and the reactant concentration

Reaction Rate LawsThe equation that expresses the mathematical relationship between the rateof a chemical reaction and the concentration of reactants is called a rate lawFor example the reaction A 0 B which is a one-step reaction has only oneactivated complex between reactants and products The rate law for this reac-tion is expressed as

where k is the specific rate constant or a numerical value that relates reac-tion rate and concentration of reactants at a given temperature Units for therate constant include L(mols) L2(mol2s) and sndash1 Depending on the reac-tion conditions especially temperature k is unique for every reaction

The rate law means that the reaction rate is directly proportional to the molarconcentration of A Thus doubling the concentration of A will double the reac-tion rate Increasing the concentration of A by a factor of 5 will increase thereaction rate by a factor of 5 The specific rate constant k does not change withconcentration however k does change with temperature A large value of kmeans that A reacts rapidly to form B What does a small value of k mean

Reaction order In the expression Rate k[A] it is understood that thenotation [A] means the same as [A]1 In other words for reactant A theunderstood exponent 1 is called the reaction order The reaction order for areactant defines how the rate is affected by the concentration of that reactantFor example the rate law for the decomposition of H2O2 is expressed by thefollowing equation

Rate k[H2O2]

Because the reaction rate is directly proportional to the concentration ofH2O2 raised to the first power [H2O2]

1 the decomposition of H2O2 is said tobe first order in H2O2 Because the reaction is first order in H2O2 the reac-tion rate changes in the same proportion that the concentration of H2O2changes So if the H2O2 concentration decreases to one-half its originalvalue the reaction rate is halved as well

Recall from Section 171 that reaction rates are determined from experi-mental data Because reaction order is based on reaction rates it follows thatreaction order also is determined experimentally Finally because the rateconstant describes the reaction rate k too must be determined experimen-tally Figure 17-14 illustrates two of several experimental methods that arecommonly used to measure reaction rates

Other reaction orders The overall reaction order of a chemical reactionis the sum of the orders for the individual reactants in the rate law Manychemical reactions particularly those having more than one reactant are notfirst order Consider the general form for a chemical reaction with two reac-tants In this chemical equation a and b are coefficients

aA bB 0 products

The general rate law for such a reaction is

Rate k[A]m[B]n

where m and n are the reaction orders for A and B respectively Only if thereaction between A and B occurs in a single step (and with a single activat-ed complex) does m a and n b Thatrsquos unlikely however because sin-gle-step reactions are uncommon

For example the reaction between nitrogen monoxide (NO) and hydrogen(H2) is described by the following equation

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

This reaction which occurs in more than one step has the following rate law

Rate k[NO]2[H2]

This rate law was determined experimentally The data tell that the ratedepends on the concentration of the reactants as follows If [NO] doubles therate quadruples if [H2] doubles the rate doubles The reaction is describedas second order in NO first order in H2 and third order overall because thesum of the orders for the individual reactants (the sum of the exponents) is(2 1) or 3

Determining Reaction OrderOne common experimental method of evaluating reaction order is called themethod of initial rates The method of initial rates determines reactionorder by comparing the initial rates of a reaction carried out with varyingreactant concentrations To understand how this method works letrsquos use thegeneral reaction aA bB 0 products Suppose that this reaction is carriedout with varying concentrations of A and B and yields the initial reactionrates shown in Table 17-3

Recall that the general rate law for this type of reaction is

Rate k[A]m[B]n

To determine m the concentrations and reaction rates in Trials 1 and 2 arecompared As you can see from the data while the concentration of Bremains constant the concentration of A in Trial 2 is twice that of Trial 1Note that the initial rate in Trial 2 is twice that of Trial 1 Because doubling[A] doubles the rate the reaction must be first order in A That is because2m 2 m must equal 1 The same method is used to determine n only thistime Trials 2 and 3 are compared Doubling the concentration of B causes therate to increase by four times Because 2n 4 n must equal 2 This infor-mation suggests that the reaction is second order in B giving the followingoverall rate law

Rate k[A]1[B]2

The overall reaction order is third order (sum of exponents 2 1 3)

The average reaction rate you learned to calculate in Section 173 givesimportant information about the reaction over a period of time Howeverchemists also may need to know at what rate the reaction is proceeding at aspecific time A pharmacist developing a new drug treatment might need toknow the progress of a reaction at an exact instant This information makesit possible to adjust the product for maximum performance Can you think ofother situations where it might be critical to know the specific reaction rateat a given time

Instantaneous Reaction RatesThe decomposition of hydrogen peroxide (H2O2) is represented as follows

2H2O2(aq) 0 2H2O(l) O2(g)

For this reaction the decrease in H2O2 concentration over time is shown inFigure 17-15 The curved line shows how the reaction rate decreases as thereaction proceeds The instantaneous rate or the rate of decomposition ata specific time can be determined by finding the slope of the straight linetangent to the curve at that instant This is because the slope of the tangentto the curve at a particular point is [H2O2]t which is one way to expressthe reaction rate In other words the rate of change in H2O2 concentrationrelates to one specific point (or instant) on the graph

Another way to determine the instantaneous rate for a chemical reactionis to use the experimentally determined rate law given the reactant concen-trations and the specific rate constant for the temperature at which the reactionoccurs For example the decomposition of dinitrogen pentoxide (N2O5) intonitrogen dioxide (NO2) and oxygen (O2) is given by the following equation

In an automobile assemblyplant the process that is mosttime consuming limits the pro-duction rate For examplebecause it takes longer to installthe onboard computer systemthan it takes to attach the hoodassembly the computer installa-tion is a rate-determining step

Reaction MechanismsMost chemical reactions consist of a sequence of two or more simpler reac-tions For example recent evidence indicates that the reaction 2O3 0 3O2occurs in three steps after intense ultraviolet radiation from the sun liberateschlorine atoms from certain compounds in Earthrsquos stratosphere Steps 1 and2 in this reaction may occur simultaneously or in reverse order

1 Chlorine atoms decompose ozone according to the equation Cl O3 0 O2 ClO

2 Ultraviolet radiation causes the decomposition reaction O3 0 O2 O

3 ClO produced in the reaction in step 1 reacts with O produced in step 2according to the equation ClO O 0 Cl O2

Each of the reactions described in steps 1 through 3 is called an elementarystep These three elementary steps comprise the complex reaction 2O3 0 3O2A complex reaction is one that consists of two or more elementary steps Thecomplete sequence of elementary steps that make up a complex reaction iscalled a reaction mechanism Adding the elementary steps in steps 1 through3 and canceling formulas that occur in equal amounts on both sides of the reac-tion arrow produce the net equation for the complex reaction as shown below

Elementary step Cl O3 0 O2 ClO

Elementary step O3 0 O2 O

Elementary step ClO O 0 Cl O2

Complex reaction 2O3 0 3O2

Because chlorine atoms react in step 1 of the reaction mechanism and arere-formed in step 3 chlorine is said to catalyze the decomposition of ozoneDo you know why Because ClO and O are formed in the reactions in steps1 and 2 respectively and are consumed in the reaction in step 3 they arecalled intermediates In a complex reaction an intermediate is a substanceproduced in one elementary step and consumed in a subsequent elementarystep Catalysts and intermediates do not appear in the net chemical equation

Rate-determining step You have probably heard the expression ldquoAchain is no stronger than its weakest linkrdquo Chemical reactions too have aldquoweakest linkrdquo in that a complex reaction can proceed no faster than theslowest of its elementary steps In other words the slowest elementary stepin a reaction mechanism limits the instantaneous rate of the overall reaction

For that reason the slowest of the elementary steps in a complex reaction iscalled the rate-determining step Figure 17-16 illustrates this concept in amanufacturing plant

To see how the rate-determining step affects reaction rate again considerthe gas-phase reaction between hydrogen and nitrogen monoxide discussedearlier in the chapter

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

A proposed mechanism for this reaction consists of the following elementarysteps

2NO 0 N2O2 (fast)

N2O2 H2 0 N2O H2O (slow)

N2O H2 0 N2 H2O (fast)

Although the first and third elementary steps occur relatively fast the mid-dle step is the slowest and it limits the overall reaction rate It is the rate-determining step The relative energy levels of reactants intermediatesproducts and activated complex are illustrated in Figure 17-17

Chemists can make use of instantaneous reaction rates reaction ordersand rate-determining steps to develop efficient ways to manufacture prod-ucts such as pharmaceuticals By knowing which step of the reaction is slow-est a chemist can work to speed up that rate-determining step and therebyincrease the rate of the overall reaction

In many models of catalytic converters this inner structure resembles tubes in a honeycomb arrangement which provides significant surface area to accommodate the catalysts

At high temperatures (300ndash500C) on the platinum catalyst surface the dangerous carbon monoxide and hydrocarbons react with oxygen to form the compounds carbon dioxide and water

Compare the amount of time itwould take this train to travelover or around the barrier withthe time it takes to travelthrough the barrier Obviouslytravel is faster through themountain with the aid of thetunnel

Note that the activation energy for the catalyzed reaction is much lower thanfor the uncatalyzed reaction The lower activation energy for the catalyzedreaction means that more collisions have sufficient energy to initiate reac-tion It might help you to visualize this relationship by thinking of the reac-tionrsquos activation energy as a mountain range to be crossed as shown inFigure 17-12 In this analogy the tunnel representing the catalyzed path-way provides an easier and therefore quicker route to the other side of themountains

Another type of substance that affects reaction rates is called an inhibitorUnlike a catalyst which speeds up reaction rates an inhibitor is a substancethat slows down or inhibits reaction rates Some inhibitors in fact actuallyprevent a reaction from happening at all

In our fast-paced world it might seem unlikely that it would be desirableto slow a reaction But if you think about your environment you can proba-bly come up with several uses for inhibitors One of the primary applicationsfor inhibitors is in the food industry where inhibitors are called preserva-tives Figure 17-13 shows how a commercially available fruit freshener

Vocabulary rate lawspecific rate constantreaction ordermethod of initial rates

In Section 171 you learned how to calculate the average rate of a chemicalreaction given the initial and final times and concentrations The word aver-age is important because most chemical reactions slow down as the reactantsare consumed To understand why most reaction rates slow over time recallthat the collision theory states that chemical reactions can occur only whenthe reacting particles collide and that reaction rate depends upon reactantconcentration As reactants are consumed fewer particles collide and thereaction slows Chemists use the concept of rate laws to quantify the resultsof the collision theory in terms of a mathematical relationship between therate of a chemical reaction and the reactant concentration

Reaction Rate LawsThe equation that expresses the mathematical relationship between the rateof a chemical reaction and the concentration of reactants is called a rate lawFor example the reaction A 0 B which is a one-step reaction has only oneactivated complex between reactants and products The rate law for this reac-tion is expressed as

where k is the specific rate constant or a numerical value that relates reac-tion rate and concentration of reactants at a given temperature Units for therate constant include L(mols) L2(mol2s) and sndash1 Depending on the reac-tion conditions especially temperature k is unique for every reaction

The rate law means that the reaction rate is directly proportional to the molarconcentration of A Thus doubling the concentration of A will double the reac-tion rate Increasing the concentration of A by a factor of 5 will increase thereaction rate by a factor of 5 The specific rate constant k does not change withconcentration however k does change with temperature A large value of kmeans that A reacts rapidly to form B What does a small value of k mean

Reaction order In the expression Rate k[A] it is understood that thenotation [A] means the same as [A]1 In other words for reactant A theunderstood exponent 1 is called the reaction order The reaction order for areactant defines how the rate is affected by the concentration of that reactantFor example the rate law for the decomposition of H2O2 is expressed by thefollowing equation

Rate k[H2O2]

Because the reaction rate is directly proportional to the concentration ofH2O2 raised to the first power [H2O2]

1 the decomposition of H2O2 is said tobe first order in H2O2 Because the reaction is first order in H2O2 the reac-tion rate changes in the same proportion that the concentration of H2O2changes So if the H2O2 concentration decreases to one-half its originalvalue the reaction rate is halved as well

Recall from Section 171 that reaction rates are determined from experi-mental data Because reaction order is based on reaction rates it follows thatreaction order also is determined experimentally Finally because the rateconstant describes the reaction rate k too must be determined experimen-tally Figure 17-14 illustrates two of several experimental methods that arecommonly used to measure reaction rates

Other reaction orders The overall reaction order of a chemical reactionis the sum of the orders for the individual reactants in the rate law Manychemical reactions particularly those having more than one reactant are notfirst order Consider the general form for a chemical reaction with two reac-tants In this chemical equation a and b are coefficients

aA bB 0 products

The general rate law for such a reaction is

Rate k[A]m[B]n

where m and n are the reaction orders for A and B respectively Only if thereaction between A and B occurs in a single step (and with a single activat-ed complex) does m a and n b Thatrsquos unlikely however because sin-gle-step reactions are uncommon

For example the reaction between nitrogen monoxide (NO) and hydrogen(H2) is described by the following equation

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

This reaction which occurs in more than one step has the following rate law

Rate k[NO]2[H2]

This rate law was determined experimentally The data tell that the ratedepends on the concentration of the reactants as follows If [NO] doubles therate quadruples if [H2] doubles the rate doubles The reaction is describedas second order in NO first order in H2 and third order overall because thesum of the orders for the individual reactants (the sum of the exponents) is(2 1) or 3

Determining Reaction OrderOne common experimental method of evaluating reaction order is called themethod of initial rates The method of initial rates determines reactionorder by comparing the initial rates of a reaction carried out with varyingreactant concentrations To understand how this method works letrsquos use thegeneral reaction aA bB 0 products Suppose that this reaction is carriedout with varying concentrations of A and B and yields the initial reactionrates shown in Table 17-3

Recall that the general rate law for this type of reaction is

Rate k[A]m[B]n

To determine m the concentrations and reaction rates in Trials 1 and 2 arecompared As you can see from the data while the concentration of Bremains constant the concentration of A in Trial 2 is twice that of Trial 1Note that the initial rate in Trial 2 is twice that of Trial 1 Because doubling[A] doubles the rate the reaction must be first order in A That is because2m 2 m must equal 1 The same method is used to determine n only thistime Trials 2 and 3 are compared Doubling the concentration of B causes therate to increase by four times Because 2n 4 n must equal 2 This infor-mation suggests that the reaction is second order in B giving the followingoverall rate law

Rate k[A]1[B]2

The overall reaction order is third order (sum of exponents 2 1 3)

The average reaction rate you learned to calculate in Section 173 givesimportant information about the reaction over a period of time Howeverchemists also may need to know at what rate the reaction is proceeding at aspecific time A pharmacist developing a new drug treatment might need toknow the progress of a reaction at an exact instant This information makesit possible to adjust the product for maximum performance Can you think ofother situations where it might be critical to know the specific reaction rateat a given time

Instantaneous Reaction RatesThe decomposition of hydrogen peroxide (H2O2) is represented as follows

2H2O2(aq) 0 2H2O(l) O2(g)

For this reaction the decrease in H2O2 concentration over time is shown inFigure 17-15 The curved line shows how the reaction rate decreases as thereaction proceeds The instantaneous rate or the rate of decomposition ata specific time can be determined by finding the slope of the straight linetangent to the curve at that instant This is because the slope of the tangentto the curve at a particular point is [H2O2]t which is one way to expressthe reaction rate In other words the rate of change in H2O2 concentrationrelates to one specific point (or instant) on the graph

Another way to determine the instantaneous rate for a chemical reactionis to use the experimentally determined rate law given the reactant concen-trations and the specific rate constant for the temperature at which the reactionoccurs For example the decomposition of dinitrogen pentoxide (N2O5) intonitrogen dioxide (NO2) and oxygen (O2) is given by the following equation

EXAMPLE PROBLEM 17-2

Calculating Instantaneous Reaction RatesThe following equation is first order in H2 and second order in NO with arate constant of 290 102 (L2(mol2middots))

2NO(g) H2(g) 0 N2O(g) H2O(g)

Calculate the instantaneous rate when the reactant concentrations are[NO] = 000200M and [H2] = 000400M

1 Analyze the ProblemThe rate law can be expressed by Rate k[NO]2[H2] Therefore the instantaneous reaction rate can be determined by insertingreactant concentrations and the specific rate constant into therate law equation

Known Unknown

[NO] 000200M Rate mol(Lmiddots)[H2] 000400Mk 290 102 (L2(mol2middots))

2 Solve for the UnknownInsert the known quantities into the rate law equation

Rate k[NO]2[H2]

Rate 290 102 (L2(mol2middots)(000200 molL)2(000400 molL))

Rate 464 106 mol(Lmiddots)

3 Evaluate the AnswerAre the units correct Units in the calculation cancel to give mol(Lmiddots)which is the common unit for the expression of reaction rates Is themagnitude reasonable A magnitude of approximately 106 mol(Lmiddots)fits with the quantities given and the rate law equation

PRACTICE PROBLEMSUse the rate law in Example Problem 17-2 and the concentrations given ineach practice problem to calculate the instantaneous rate for the reactionbetween NO and H2

24 [NO] 000500M and [H2] 000200M

25 [NO] 00100M and [H2] 000125M

26 [NO] 000446M and [H2] 000282M

The experimentally determined rate law for this reaction is

Rate k[N2O5]

where k 10 105 s1 If [N2O5] 0350M the instantaneous reactionrate would be calculated as

In an automobile assemblyplant the process that is mosttime consuming limits the pro-duction rate For examplebecause it takes longer to installthe onboard computer systemthan it takes to attach the hoodassembly the computer installa-tion is a rate-determining step

Reaction MechanismsMost chemical reactions consist of a sequence of two or more simpler reac-tions For example recent evidence indicates that the reaction 2O3 0 3O2occurs in three steps after intense ultraviolet radiation from the sun liberateschlorine atoms from certain compounds in Earthrsquos stratosphere Steps 1 and2 in this reaction may occur simultaneously or in reverse order

1 Chlorine atoms decompose ozone according to the equation Cl O3 0 O2 ClO

2 Ultraviolet radiation causes the decomposition reaction O3 0 O2 O

3 ClO produced in the reaction in step 1 reacts with O produced in step 2according to the equation ClO O 0 Cl O2

Each of the reactions described in steps 1 through 3 is called an elementarystep These three elementary steps comprise the complex reaction 2O3 0 3O2A complex reaction is one that consists of two or more elementary steps Thecomplete sequence of elementary steps that make up a complex reaction iscalled a reaction mechanism Adding the elementary steps in steps 1 through3 and canceling formulas that occur in equal amounts on both sides of the reac-tion arrow produce the net equation for the complex reaction as shown below

Elementary step Cl O3 0 O2 ClO

Elementary step O3 0 O2 O

Elementary step ClO O 0 Cl O2

Complex reaction 2O3 0 3O2

Because chlorine atoms react in step 1 of the reaction mechanism and arere-formed in step 3 chlorine is said to catalyze the decomposition of ozoneDo you know why Because ClO and O are formed in the reactions in steps1 and 2 respectively and are consumed in the reaction in step 3 they arecalled intermediates In a complex reaction an intermediate is a substanceproduced in one elementary step and consumed in a subsequent elementarystep Catalysts and intermediates do not appear in the net chemical equation

Rate-determining step You have probably heard the expression ldquoAchain is no stronger than its weakest linkrdquo Chemical reactions too have aldquoweakest linkrdquo in that a complex reaction can proceed no faster than theslowest of its elementary steps In other words the slowest elementary stepin a reaction mechanism limits the instantaneous rate of the overall reaction

For that reason the slowest of the elementary steps in a complex reaction iscalled the rate-determining step Figure 17-16 illustrates this concept in amanufacturing plant

To see how the rate-determining step affects reaction rate again considerthe gas-phase reaction between hydrogen and nitrogen monoxide discussedearlier in the chapter

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

A proposed mechanism for this reaction consists of the following elementarysteps

2NO 0 N2O2 (fast)

N2O2 H2 0 N2O H2O (slow)

N2O H2 0 N2 H2O (fast)

Although the first and third elementary steps occur relatively fast the mid-dle step is the slowest and it limits the overall reaction rate It is the rate-determining step The relative energy levels of reactants intermediatesproducts and activated complex are illustrated in Figure 17-17

Chemists can make use of instantaneous reaction rates reaction ordersand rate-determining steps to develop efficient ways to manufacture prod-ucts such as pharmaceuticals By knowing which step of the reaction is slow-est a chemist can work to speed up that rate-determining step and therebyincrease the rate of the overall reaction

In Section 171 you learned how to calculate the average rate of a chemicalreaction given the initial and final times and concentrations The word aver-age is important because most chemical reactions slow down as the reactantsare consumed To understand why most reaction rates slow over time recallthat the collision theory states that chemical reactions can occur only whenthe reacting particles collide and that reaction rate depends upon reactantconcentration As reactants are consumed fewer particles collide and thereaction slows Chemists use the concept of rate laws to quantify the resultsof the collision theory in terms of a mathematical relationship between therate of a chemical reaction and the reactant concentration

Reaction Rate LawsThe equation that expresses the mathematical relationship between the rateof a chemical reaction and the concentration of reactants is called a rate lawFor example the reaction A 0 B which is a one-step reaction has only oneactivated complex between reactants and products The rate law for this reac-tion is expressed as

where k is the specific rate constant or a numerical value that relates reac-tion rate and concentration of reactants at a given temperature Units for therate constant include L(mols) L2(mol2s) and sndash1 Depending on the reac-tion conditions especially temperature k is unique for every reaction

The rate law means that the reaction rate is directly proportional to the molarconcentration of A Thus doubling the concentration of A will double the reac-tion rate Increasing the concentration of A by a factor of 5 will increase thereaction rate by a factor of 5 The specific rate constant k does not change withconcentration however k does change with temperature A large value of kmeans that A reacts rapidly to form B What does a small value of k mean

Reaction order In the expression Rate k[A] it is understood that thenotation [A] means the same as [A]1 In other words for reactant A theunderstood exponent 1 is called the reaction order The reaction order for areactant defines how the rate is affected by the concentration of that reactantFor example the rate law for the decomposition of H2O2 is expressed by thefollowing equation

Rate k[H2O2]

Because the reaction rate is directly proportional to the concentration ofH2O2 raised to the first power [H2O2]

1 the decomposition of H2O2 is said tobe first order in H2O2 Because the reaction is first order in H2O2 the reac-tion rate changes in the same proportion that the concentration of H2O2changes So if the H2O2 concentration decreases to one-half its originalvalue the reaction rate is halved as well

Recall from Section 171 that reaction rates are determined from experi-mental data Because reaction order is based on reaction rates it follows thatreaction order also is determined experimentally Finally because the rateconstant describes the reaction rate k too must be determined experimen-tally Figure 17-14 illustrates two of several experimental methods that arecommonly used to measure reaction rates

Other reaction orders The overall reaction order of a chemical reactionis the sum of the orders for the individual reactants in the rate law Manychemical reactions particularly those having more than one reactant are notfirst order Consider the general form for a chemical reaction with two reac-tants In this chemical equation a and b are coefficients

aA bB 0 products

The general rate law for such a reaction is

Rate k[A]m[B]n

where m and n are the reaction orders for A and B respectively Only if thereaction between A and B occurs in a single step (and with a single activat-ed complex) does m a and n b Thatrsquos unlikely however because sin-gle-step reactions are uncommon

For example the reaction between nitrogen monoxide (NO) and hydrogen(H2) is described by the following equation

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

This reaction which occurs in more than one step has the following rate law

Rate k[NO]2[H2]

This rate law was determined experimentally The data tell that the ratedepends on the concentration of the reactants as follows If [NO] doubles therate quadruples if [H2] doubles the rate doubles The reaction is describedas second order in NO first order in H2 and third order overall because thesum of the orders for the individual reactants (the sum of the exponents) is(2 1) or 3

Determining Reaction OrderOne common experimental method of evaluating reaction order is called themethod of initial rates The method of initial rates determines reactionorder by comparing the initial rates of a reaction carried out with varyingreactant concentrations To understand how this method works letrsquos use thegeneral reaction aA bB 0 products Suppose that this reaction is carriedout with varying concentrations of A and B and yields the initial reactionrates shown in Table 17-3

Recall that the general rate law for this type of reaction is

To determine m the concentrations and reaction rates in Trials 1 and 2 arecompared As you can see from the data while the concentration of Bremains constant the concentration of A in Trial 2 is twice that of Trial 1Note that the initial rate in Trial 2 is twice that of Trial 1 Because doubling[A] doubles the rate the reaction must be first order in A That is because2m 2 m must equal 1 The same method is used to determine n only thistime Trials 2 and 3 are compared Doubling the concentration of B causes therate to increase by four times Because 2n 4 n must equal 2 This infor-mation suggests that the reaction is second order in B giving the followingoverall rate law

Rate k[A]1[B]2

The overall reaction order is third order (sum of exponents 2 1 3)

Instantaneous Reaction Ratesand Reaction Mechanisms

Vocabularyinstantaneous ratecomplex reactionreaction mechanismintermediaterate-determining step

The average reaction rate you learned to calculate in Section 173 givesimportant information about the reaction over a period of time Howeverchemists also may need to know at what rate the reaction is proceeding at aspecific time A pharmacist developing a new drug treatment might need toknow the progress of a reaction at an exact instant This information makesit possible to adjust the product for maximum performance Can you think ofother situations where it might be critical to know the specific reaction rateat a given time

Instantaneous Reaction RatesThe decomposition of hydrogen peroxide (H2O2) is represented as follows

2H2O2(aq) 0 2H2O(l) O2(g)

For this reaction the decrease in H2O2 concentration over time is shown inFigure 17-15 The curved line shows how the reaction rate decreases as thereaction proceeds The instantaneous rate or the rate of decomposition ata specific time can be determined by finding the slope of the straight linetangent to the curve at that instant This is because the slope of the tangentto the curve at a particular point is [H2O2]t which is one way to expressthe reaction rate In other words the rate of change in H2O2 concentrationrelates to one specific point (or instant) on the graph

Another way to determine the instantaneous rate for a chemical reactionis to use the experimentally determined rate law given the reactant concen-trations and the specific rate constant for the temperature at which the reactionoccurs For example the decomposition of dinitrogen pentoxide (N2O5) intonitrogen dioxide (NO2) and oxygen (O2) is given by the following equation

EXAMPLE PROBLEM 17-2

Calculating Instantaneous Reaction RatesThe following equation is first order in H2 and second order in NO with arate constant of 290 102 (L2(mol2middots))

2NO(g) H2(g) 0 N2O(g) H2O(g)

Calculate the instantaneous rate when the reactant concentrations are[NO] = 000200M and [H2] = 000400M

1 Analyze the ProblemThe rate law can be expressed by Rate k[NO]2[H2] Therefore the instantaneous reaction rate can be determined by insertingreactant concentrations and the specific rate constant into therate law equation

Known Unknown

[NO] 000200M Rate mol(Lmiddots)[H2] 000400Mk 290 102 (L2(mol2middots))

2 Solve for the UnknownInsert the known quantities into the rate law equation

Rate k[NO]2[H2]

Rate 290 102 (L2(mol2middots)(000200 molL)2(000400 molL))

Rate 464 106 mol(Lmiddots)

3 Evaluate the AnswerAre the units correct Units in the calculation cancel to give mol(Lmiddots)which is the common unit for the expression of reaction rates Is themagnitude reasonable A magnitude of approximately 106 mol(Lmiddots)fits with the quantities given and the rate law equation

PRACTICE PROBLEMSUse the rate law in Example Problem 17-2 and the concentrations given ineach practice problem to calculate the instantaneous rate for the reactionbetween NO and H2

24 [NO] 000500M and [H2] 000200M

25 [NO] 00100M and [H2] 000125M

26 [NO] 000446M and [H2] 000282M

The experimentally determined rate law for this reaction is

Rate k[N2O5]

where k 10 105 s1 If [N2O5] 0350M the instantaneous reactionrate would be calculated as

In an automobile assemblyplant the process that is mosttime consuming limits the pro-duction rate For examplebecause it takes longer to installthe onboard computer systemthan it takes to attach the hoodassembly the computer installa-tion is a rate-determining step

Reaction MechanismsMost chemical reactions consist of a sequence of two or more simpler reac-tions For example recent evidence indicates that the reaction 2O3 0 3O2occurs in three steps after intense ultraviolet radiation from the sun liberateschlorine atoms from certain compounds in Earthrsquos stratosphere Steps 1 and2 in this reaction may occur simultaneously or in reverse order

1 Chlorine atoms decompose ozone according to the equation Cl O3 0 O2 ClO

2 Ultraviolet radiation causes the decomposition reaction O3 0 O2 O

3 ClO produced in the reaction in step 1 reacts with O produced in step 2according to the equation ClO O 0 Cl O2

Each of the reactions described in steps 1 through 3 is called an elementarystep These three elementary steps comprise the complex reaction 2O3 0 3O2A complex reaction is one that consists of two or more elementary steps Thecomplete sequence of elementary steps that make up a complex reaction iscalled a reaction mechanism Adding the elementary steps in steps 1 through3 and canceling formulas that occur in equal amounts on both sides of the reac-tion arrow produce the net equation for the complex reaction as shown below

Elementary step Cl O3 0 O2 ClO

Elementary step O3 0 O2 O

Elementary step ClO O 0 Cl O2

Complex reaction 2O3 0 3O2

Because chlorine atoms react in step 1 of the reaction mechanism and arere-formed in step 3 chlorine is said to catalyze the decomposition of ozoneDo you know why Because ClO and O are formed in the reactions in steps1 and 2 respectively and are consumed in the reaction in step 3 they arecalled intermediates In a complex reaction an intermediate is a substanceproduced in one elementary step and consumed in a subsequent elementarystep Catalysts and intermediates do not appear in the net chemical equation

Rate-determining step You have probably heard the expression ldquoAchain is no stronger than its weakest linkrdquo Chemical reactions too have aldquoweakest linkrdquo in that a complex reaction can proceed no faster than theslowest of its elementary steps In other words the slowest elementary stepin a reaction mechanism limits the instantaneous rate of the overall reaction

For that reason the slowest of the elementary steps in a complex reaction iscalled the rate-determining step Figure 17-16 illustrates this concept in amanufacturing plant

To see how the rate-determining step affects reaction rate again considerthe gas-phase reaction between hydrogen and nitrogen monoxide discussedearlier in the chapter

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

A proposed mechanism for this reaction consists of the following elementarysteps

2NO 0 N2O2 (fast)

N2O2 H2 0 N2O H2O (slow)

N2O H2 0 N2 H2O (fast)

Although the first and third elementary steps occur relatively fast the mid-dle step is the slowest and it limits the overall reaction rate It is the rate-determining step The relative energy levels of reactants intermediatesproducts and activated complex are illustrated in Figure 17-17

Chemists can make use of instantaneous reaction rates reaction ordersand rate-determining steps to develop efficient ways to manufacture prod-ucts such as pharmaceuticals By knowing which step of the reaction is slow-est a chemist can work to speed up that rate-determining step and therebyincrease the rate of the overall reaction

In Section 171 you learned how to calculate the average rate of a chemicalreaction given the initial and final times and concentrations The word aver-age is important because most chemical reactions slow down as the reactantsare consumed To understand why most reaction rates slow over time recallthat the collision theory states that chemical reactions can occur only whenthe reacting particles collide and that reaction rate depends upon reactantconcentration As reactants are consumed fewer particles collide and thereaction slows Chemists use the concept of rate laws to quantify the resultsof the collision theory in terms of a mathematical relationship between therate of a chemical reaction and the reactant concentration

Reaction Rate LawsThe equation that expresses the mathematical relationship between the rateof a chemical reaction and the concentration of reactants is called a rate lawFor example the reaction A 0 B which is a one-step reaction has only oneactivated complex between reactants and products The rate law for this reac-tion is expressed as

where k is the specific rate constant or a numerical value that relates reac-tion rate and concentration of reactants at a given temperature Units for therate constant include L(mols) L2(mol2s) and sndash1 Depending on the reac-tion conditions especially temperature k is unique for every reaction

The rate law means that the reaction rate is directly proportional to the molarconcentration of A Thus doubling the concentration of A will double the reac-tion rate Increasing the concentration of A by a factor of 5 will increase thereaction rate by a factor of 5 The specific rate constant k does not change withconcentration however k does change with temperature A large value of kmeans that A reacts rapidly to form B What does a small value of k mean

Reaction order In the expression Rate k[A] it is understood that thenotation [A] means the same as [A]1 In other words for reactant A theunderstood exponent 1 is called the reaction order The reaction order for areactant defines how the rate is affected by the concentration of that reactantFor example the rate law for the decomposition of H2O2 is expressed by thefollowing equation

Rate k[H2O2]

Because the reaction rate is directly proportional to the concentration ofH2O2 raised to the first power [H2O2]

1 the decomposition of H2O2 is said tobe first order in H2O2 Because the reaction is first order in H2O2 the reac-tion rate changes in the same proportion that the concentration of H2O2changes So if the H2O2 concentration decreases to one-half its originalvalue the reaction rate is halved as well

Recall from Section 171 that reaction rates are determined from experi-mental data Because reaction order is based on reaction rates it follows thatreaction order also is determined experimentally Finally because the rateconstant describes the reaction rate k too must be determined experimen-tally Figure 17-14 illustrates two of several experimental methods that arecommonly used to measure reaction rates

Other reaction orders The overall reaction order of a chemical reactionis the sum of the orders for the individual reactants in the rate law Manychemical reactions particularly those having more than one reactant are notfirst order Consider the general form for a chemical reaction with two reac-tants In this chemical equation a and b are coefficients

aA bB 0 products

The general rate law for such a reaction is

Rate k[A]m[B]n

where m and n are the reaction orders for A and B respectively Only if thereaction between A and B occurs in a single step (and with a single activat-ed complex) does m a and n b Thatrsquos unlikely however because sin-gle-step reactions are uncommon

This rate law was determined experimentally The data tell that the ratedepends on the concentration of the reactants as follows If [NO] doubles therate quadruples if [H2] doubles the rate doubles The reaction is describedas second order in NO first order in H2 and third order overall because thesum of the orders for the individual reactants (the sum of the exponents) is(2 1) or 3

Determining Reaction OrderOne common experimental method of evaluating reaction order is called themethod of initial rates The method of initial rates determines reactionorder by comparing the initial rates of a reaction carried out with varyingreactant concentrations To understand how this method works letrsquos use thegeneral reaction aA bB 0 products Suppose that this reaction is carriedout with varying concentrations of A and B and yields the initial reactionrates shown in Table 17-3

Recall that the general rate law for this type of reaction is

Rate k[A]m[B]n

To determine m the concentrations and reaction rates in Trials 1 and 2 arecompared As you can see from the data while the concentration of Bremains constant the concentration of A in Trial 2 is twice that of Trial 1Note that the initial rate in Trial 2 is twice that of Trial 1 Because doubling[A] doubles the rate the reaction must be first order in A That is because2m 2 m must equal 1 The same method is used to determine n only thistime Trials 2 and 3 are compared Doubling the concentration of B causes therate to increase by four times Because 2n 4 n must equal 2 This infor-mation suggests that the reaction is second order in B giving the followingoverall rate law

Rate k[A]1[B]2

The overall reaction order is third order (sum of exponents 2 1 3)

Instantaneous Reaction Ratesand Reaction Mechanisms

Vocabularyinstantaneous ratecomplex reactionreaction mechanismintermediaterate-determining step

The average reaction rate you learned to calculate in Section 173 givesimportant information about the reaction over a period of time Howeverchemists also may need to know at what rate the reaction is proceeding at aspecific time A pharmacist developing a new drug treatment might need toknow the progress of a reaction at an exact instant This information makesit possible to adjust the product for maximum performance Can you think ofother situations where it might be critical to know the specific reaction rateat a given time

Instantaneous Reaction RatesThe decomposition of hydrogen peroxide (H2O2) is represented as follows

2H2O2(aq) 0 2H2O(l) O2(g)

For this reaction the decrease in H2O2 concentration over time is shown inFigure 17-15 The curved line shows how the reaction rate decreases as thereaction proceeds The instantaneous rate or the rate of decomposition ata specific time can be determined by finding the slope of the straight linetangent to the curve at that instant This is because the slope of the tangentto the curve at a particular point is [H2O2]t which is one way to expressthe reaction rate In other words the rate of change in H2O2 concentrationrelates to one specific point (or instant) on the graph

Another way to determine the instantaneous rate for a chemical reactionis to use the experimentally determined rate law given the reactant concen-trations and the specific rate constant for the temperature at which the reactionoccurs For example the decomposition of dinitrogen pentoxide (N2O5) intonitrogen dioxide (NO2) and oxygen (O2) is given by the following equation

2NO(g) H2(g) 0 N2O(g) H2O(g)

Calculate the instantaneous rate when the reactant concentrations are[NO] = 000200M and [H2] = 000400M

1 Analyze the ProblemThe rate law can be expressed by Rate k[NO]2[H2] Therefore the instantaneous reaction rate can be determined by insertingreactant concentrations and the specific rate constant into therate law equation

Known Unknown

[NO] 000200M Rate mol(Lmiddots)[H2] 000400Mk 290 102 (L2(mol2middots))

2 Solve for the UnknownInsert the known quantities into the rate law equation

Rate k[NO]2[H2]

Rate 290 102 (L2(mol2middots)(000200 molL)2(000400 molL))

Rate 464 106 mol(Lmiddots)

3 Evaluate the AnswerAre the units correct Units in the calculation cancel to give mol(Lmiddots)which is the common unit for the expression of reaction rates Is themagnitude reasonable A magnitude of approximately 106 mol(Lmiddots)fits with the quantities given and the rate law equation

PRACTICE PROBLEMSUse the rate law in Example Problem 17-2 and the concentrations given ineach practice problem to calculate the instantaneous rate for the reactionbetween NO and H2

In an automobile assemblyplant the process that is mosttime consuming limits the pro-duction rate For examplebecause it takes longer to installthe onboard computer systemthan it takes to attach the hoodassembly the computer installa-tion is a rate-determining step

Reaction MechanismsMost chemical reactions consist of a sequence of two or more simpler reac-tions For example recent evidence indicates that the reaction 2O3 0 3O2occurs in three steps after intense ultraviolet radiation from the sun liberateschlorine atoms from certain compounds in Earthrsquos stratosphere Steps 1 and2 in this reaction may occur simultaneously or in reverse order

1 Chlorine atoms decompose ozone according to the equation Cl O3 0 O2 ClO

2 Ultraviolet radiation causes the decomposition reaction O3 0 O2 O

3 ClO produced in the reaction in step 1 reacts with O produced in step 2according to the equation ClO O 0 Cl O2

Each of the reactions described in steps 1 through 3 is called an elementarystep These three elementary steps comprise the complex reaction 2O3 0 3O2A complex reaction is one that consists of two or more elementary steps Thecomplete sequence of elementary steps that make up a complex reaction iscalled a reaction mechanism Adding the elementary steps in steps 1 through3 and canceling formulas that occur in equal amounts on both sides of the reac-tion arrow produce the net equation for the complex reaction as shown below

Elementary step Cl O3 0 O2 ClO

Elementary step O3 0 O2 O

Elementary step ClO O 0 Cl O2

Complex reaction 2O3 0 3O2

Because chlorine atoms react in step 1 of the reaction mechanism and arere-formed in step 3 chlorine is said to catalyze the decomposition of ozoneDo you know why Because ClO and O are formed in the reactions in steps1 and 2 respectively and are consumed in the reaction in step 3 they arecalled intermediates In a complex reaction an intermediate is a substanceproduced in one elementary step and consumed in a subsequent elementarystep Catalysts and intermediates do not appear in the net chemical equation

Rate-determining step You have probably heard the expression ldquoAchain is no stronger than its weakest linkrdquo Chemical reactions too have aldquoweakest linkrdquo in that a complex reaction can proceed no faster than theslowest of its elementary steps In other words the slowest elementary stepin a reaction mechanism limits the instantaneous rate of the overall reaction

For that reason the slowest of the elementary steps in a complex reaction iscalled the rate-determining step Figure 17-16 illustrates this concept in amanufacturing plant

To see how the rate-determining step affects reaction rate again considerthe gas-phase reaction between hydrogen and nitrogen monoxide discussedearlier in the chapter

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

A proposed mechanism for this reaction consists of the following elementarysteps

2NO 0 N2O2 (fast)

N2O2 H2 0 N2O H2O (slow)

N2O H2 0 N2 H2O (fast)

Although the first and third elementary steps occur relatively fast the mid-dle step is the slowest and it limits the overall reaction rate It is the rate-determining step The relative energy levels of reactants intermediatesproducts and activated complex are illustrated in Figure 17-17

Chemists can make use of instantaneous reaction rates reaction ordersand rate-determining steps to develop efficient ways to manufacture prod-ucts such as pharmaceuticals By knowing which step of the reaction is slow-est a chemist can work to speed up that rate-determining step and therebyincrease the rate of the overall reaction

Reaction order In the expression Rate k[A] it is understood that thenotation [A] means the same as [A]1 In other words for reactant A theunderstood exponent 1 is called the reaction order The reaction order for areactant defines how the rate is affected by the concentration of that reactantFor example the rate law for the decomposition of H2O2 is expressed by thefollowing equation

Rate k[H2O2]

Because the reaction rate is directly proportional to the concentration ofH2O2 raised to the first power [H2O2]

1 the decomposition of H2O2 is said tobe first order in H2O2 Because the reaction is first order in H2O2 the reac-tion rate changes in the same proportion that the concentration of H2O2changes So if the H2O2 concentration decreases to one-half its originalvalue the reaction rate is halved as well

Recall from Section 171 that reaction rates are determined from experi-mental data Because reaction order is based on reaction rates it follows thatreaction order also is determined experimentally Finally because the rateconstant describes the reaction rate k too must be determined experimen-tally Figure 17-14 illustrates two of several experimental methods that arecommonly used to measure reaction rates

Other reaction orders The overall reaction order of a chemical reactionis the sum of the orders for the individual reactants in the rate law Manychemical reactions particularly those having more than one reactant are notfirst order Consider the general form for a chemical reaction with two reac-tants In this chemical equation a and b are coefficients

aA bB 0 products

The general rate law for such a reaction is

Rate k[A]m[B]n

where m and n are the reaction orders for A and B respectively Only if thereaction between A and B occurs in a single step (and with a single activat-ed complex) does m a and n b Thatrsquos unlikely however because sin-gle-step reactions are uncommon

For example the reaction between nitrogen monoxide (NO) and hydrogen(H2) is described by the following equation

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

This reaction which occurs in more than one step has the following rate law

Rate k[NO]2[H2]

This rate law was determined experimentally The data tell that the ratedepends on the concentration of the reactants as follows If [NO] doubles therate quadruples if [H2] doubles the rate doubles The reaction is describedas second order in NO first order in H2 and third order overall because thesum of the orders for the individual reactants (the sum of the exponents) is(2 1) or 3

Determining Reaction OrderOne common experimental method of evaluating reaction order is called themethod of initial rates The method of initial rates determines reactionorder by comparing the initial rates of a reaction carried out with varyingreactant concentrations To understand how this method works letrsquos use thegeneral reaction aA bB 0 products Suppose that this reaction is carriedout with varying concentrations of A and B and yields the initial reactionrates shown in Table 17-3

Recall that the general rate law for this type of reaction is

Rate k[A]m[B]n

To determine m the concentrations and reaction rates in Trials 1 and 2 arecompared As you can see from the data while the concentration of Bremains constant the concentration of A in Trial 2 is twice that of Trial 1Note that the initial rate in Trial 2 is twice that of Trial 1 Because doubling[A] doubles the rate the reaction must be first order in A That is because2m 2 m must equal 1 The same method is used to determine n only thistime Trials 2 and 3 are compared Doubling the concentration of B causes therate to increase by four times Because 2n 4 n must equal 2 This infor-mation suggests that the reaction is second order in B giving the followingoverall rate law

Rate k[A]1[B]2

The overall reaction order is third order (sum of exponents 2 1 3)

Instantaneous Reaction Ratesand Reaction Mechanisms

Objectivesbull Calculate instantaneous

The average reaction rate you learned to calculate in Section 173 givesimportant information about the reaction over a period of time Howeverchemists also may need to know at what rate the reaction is proceeding at aspecific time A pharmacist developing a new drug treatment might need toknow the progress of a reaction at an exact instant This information makesit possible to adjust the product for maximum performance Can you think ofother situations where it might be critical to know the specific reaction rateat a given time

Instantaneous Reaction RatesThe decomposition of hydrogen peroxide (H2O2) is represented as follows

2H2O2(aq) 0 2H2O(l) O2(g)

For this reaction the decrease in H2O2 concentration over time is shown inFigure 17-15 The curved line shows how the reaction rate decreases as thereaction proceeds The instantaneous rate or the rate of decomposition ata specific time can be determined by finding the slope of the straight linetangent to the curve at that instant This is because the slope of the tangentto the curve at a particular point is [H2O2]t which is one way to expressthe reaction rate In other words the rate of change in H2O2 concentrationrelates to one specific point (or instant) on the graph

Another way to determine the instantaneous rate for a chemical reactionis to use the experimentally determined rate law given the reactant concen-trations and the specific rate constant for the temperature at which the reactionoccurs For example the decomposition of dinitrogen pentoxide (N2O5) intonitrogen dioxide (NO2) and oxygen (O2) is given by the following equation

EXAMPLE PROBLEM 17-2

Calculating Instantaneous Reaction RatesThe following equation is first order in H2 and second order in NO with arate constant of 290 102 (L2(mol2middots))

2NO(g) H2(g) 0 N2O(g) H2O(g)

Calculate the instantaneous rate when the reactant concentrations are[NO] = 000200M and [H2] = 000400M

1 Analyze the ProblemThe rate law can be expressed by Rate k[NO]2[H2] Therefore the instantaneous reaction rate can be determined by insertingreactant concentrations and the specific rate constant into therate law equation

Known Unknown

[NO] 000200M Rate mol(Lmiddots)[H2] 000400Mk 290 102 (L2(mol2middots))

2 Solve for the UnknownInsert the known quantities into the rate law equation

Rate k[NO]2[H2]

Rate 290 102 (L2(mol2middots)(000200 molL)2(000400 molL))

Rate 464 106 mol(Lmiddots)

3 Evaluate the AnswerAre the units correct Units in the calculation cancel to give mol(Lmiddots)which is the common unit for the expression of reaction rates Is themagnitude reasonable A magnitude of approximately 106 mol(Lmiddots)fits with the quantities given and the rate law equation

PRACTICE PROBLEMSUse the rate law in Example Problem 17-2 and the concentrations given ineach practice problem to calculate the instantaneous rate for the reactionbetween NO and H2

25 [NO] 00100M and [H2] 000125M

26 [NO] 000446M and [H2] 000282M

The experimentally determined rate law for this reaction is

Rate k[N2O5]

where k 10 105 s1 If [N2O5] 0350M the instantaneous reactionrate would be calculated as

In an automobile assemblyplant the process that is mosttime consuming limits the pro-duction rate For examplebecause it takes longer to installthe onboard computer systemthan it takes to attach the hoodassembly the computer installa-tion is a rate-determining step

Reaction MechanismsMost chemical reactions consist of a sequence of two or more simpler reac-tions For example recent evidence indicates that the reaction 2O3 0 3O2occurs in three steps after intense ultraviolet radiation from the sun liberateschlorine atoms from certain compounds in Earthrsquos stratosphere Steps 1 and2 in this reaction may occur simultaneously or in reverse order

1 Chlorine atoms decompose ozone according to the equation Cl O3 0 O2 ClO

2 Ultraviolet radiation causes the decomposition reaction O3 0 O2 O

3 ClO produced in the reaction in step 1 reacts with O produced in step 2according to the equation ClO O 0 Cl O2

Each of the reactions described in steps 1 through 3 is called an elementarystep These three elementary steps comprise the complex reaction 2O3 0 3O2A complex reaction is one that consists of two or more elementary steps Thecomplete sequence of elementary steps that make up a complex reaction iscalled a reaction mechanism Adding the elementary steps in steps 1 through3 and canceling formulas that occur in equal amounts on both sides of the reac-tion arrow produce the net equation for the complex reaction as shown below

Elementary step Cl O3 0 O2 ClO

Elementary step O3 0 O2 O

Elementary step ClO O 0 Cl O2

Complex reaction 2O3 0 3O2

Because chlorine atoms react in step 1 of the reaction mechanism and arere-formed in step 3 chlorine is said to catalyze the decomposition of ozoneDo you know why Because ClO and O are formed in the reactions in steps1 and 2 respectively and are consumed in the reaction in step 3 they arecalled intermediates In a complex reaction an intermediate is a substanceproduced in one elementary step and consumed in a subsequent elementarystep Catalysts and intermediates do not appear in the net chemical equation

Rate-determining step You have probably heard the expression ldquoAchain is no stronger than its weakest linkrdquo Chemical reactions too have aldquoweakest linkrdquo in that a complex reaction can proceed no faster than theslowest of its elementary steps In other words the slowest elementary stepin a reaction mechanism limits the instantaneous rate of the overall reaction

For that reason the slowest of the elementary steps in a complex reaction iscalled the rate-determining step Figure 17-16 illustrates this concept in amanufacturing plant

To see how the rate-determining step affects reaction rate again considerthe gas-phase reaction between hydrogen and nitrogen monoxide discussedearlier in the chapter

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

A proposed mechanism for this reaction consists of the following elementarysteps

2NO 0 N2O2 (fast)

N2O2 H2 0 N2O H2O (slow)

N2O H2 0 N2 H2O (fast)

Although the first and third elementary steps occur relatively fast the mid-dle step is the slowest and it limits the overall reaction rate It is the rate-determining step The relative energy levels of reactants intermediatesproducts and activated complex are illustrated in Figure 17-17

Chemists can make use of instantaneous reaction rates reaction ordersand rate-determining steps to develop efficient ways to manufacture prod-ucts such as pharmaceuticals By knowing which step of the reaction is slow-est a chemist can work to speed up that rate-determining step and therebyincrease the rate of the overall reaction

For example the reaction between nitrogen monoxide (NO) and hydrogen(H2) is described by the following equation

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

This reaction which occurs in more than one step has the following rate law

Rate k[NO]2[H2]

This rate law was determined experimentally The data tell that the ratedepends on the concentration of the reactants as follows If [NO] doubles therate quadruples if [H2] doubles the rate doubles The reaction is describedas second order in NO first order in H2 and third order overall because thesum of the orders for the individual reactants (the sum of the exponents) is(2 1) or 3

Determining Reaction OrderOne common experimental method of evaluating reaction order is called themethod of initial rates The method of initial rates determines reactionorder by comparing the initial rates of a reaction carried out with varyingreactant concentrations To understand how this method works letrsquos use thegeneral reaction aA bB 0 products Suppose that this reaction is carriedout with varying concentrations of A and B and yields the initial reactionrates shown in Table 17-3

Recall that the general rate law for this type of reaction is

Rate k[A]m[B]n

To determine m the concentrations and reaction rates in Trials 1 and 2 arecompared As you can see from the data while the concentration of Bremains constant the concentration of A in Trial 2 is twice that of Trial 1Note that the initial rate in Trial 2 is twice that of Trial 1 Because doubling[A] doubles the rate the reaction must be first order in A That is because2m 2 m must equal 1 The same method is used to determine n only thistime Trials 2 and 3 are compared Doubling the concentration of B causes therate to increase by four times Because 2n 4 n must equal 2 This infor-mation suggests that the reaction is second order in B giving the followingoverall rate law

Rate k[A]1[B]2

The overall reaction order is third order (sum of exponents 2 1 3)

The average reaction rate you learned to calculate in Section 173 givesimportant information about the reaction over a period of time Howeverchemists also may need to know at what rate the reaction is proceeding at aspecific time A pharmacist developing a new drug treatment might need toknow the progress of a reaction at an exact instant This information makesit possible to adjust the product for maximum performance Can you think ofother situations where it might be critical to know the specific reaction rateat a given time

Instantaneous Reaction RatesThe decomposition of hydrogen peroxide (H2O2) is represented as follows

2H2O2(aq) 0 2H2O(l) O2(g)

For this reaction the decrease in H2O2 concentration over time is shown inFigure 17-15 The curved line shows how the reaction rate decreases as thereaction proceeds The instantaneous rate or the rate of decomposition ata specific time can be determined by finding the slope of the straight linetangent to the curve at that instant This is because the slope of the tangentto the curve at a particular point is [H2O2]t which is one way to expressthe reaction rate In other words the rate of change in H2O2 concentrationrelates to one specific point (or instant) on the graph

Another way to determine the instantaneous rate for a chemical reactionis to use the experimentally determined rate law given the reactant concen-trations and the specific rate constant for the temperature at which the reactionoccurs For example the decomposition of dinitrogen pentoxide (N2O5) intonitrogen dioxide (NO2) and oxygen (O2) is given by the following equation

EXAMPLE PROBLEM 17-2

Calculating Instantaneous Reaction RatesThe following equation is first order in H2 and second order in NO with arate constant of 290 102 (L2(mol2middots))

2NO(g) H2(g) 0 N2O(g) H2O(g)

Calculate the instantaneous rate when the reactant concentrations are[NO] = 000200M and [H2] = 000400M

1 Analyze the ProblemThe rate law can be expressed by Rate k[NO]2[H2] Therefore the instantaneous reaction rate can be determined by insertingreactant concentrations and the specific rate constant into therate law equation

Known Unknown

[NO] 000200M Rate mol(Lmiddots)[H2] 000400Mk 290 102 (L2(mol2middots))

2 Solve for the UnknownInsert the known quantities into the rate law equation

Rate k[NO]2[H2]

Rate 290 102 (L2(mol2middots)(000200 molL)2(000400 molL))

Rate 464 106 mol(Lmiddots)

3 Evaluate the AnswerAre the units correct Units in the calculation cancel to give mol(Lmiddots)which is the common unit for the expression of reaction rates Is themagnitude reasonable A magnitude of approximately 106 mol(Lmiddots)fits with the quantities given and the rate law equation

PRACTICE PROBLEMSUse the rate law in Example Problem 17-2 and the concentrations given ineach practice problem to calculate the instantaneous rate for the reactionbetween NO and H2

24 [NO] 000500M and [H2] 000200M

25 [NO] 00100M and [H2] 000125M

26 [NO] 000446M and [H2] 000282M

The experimentally determined rate law for this reaction is

Rate k[N2O5]

where k 10 105 s1 If [N2O5] 0350M the instantaneous reactionrate would be calculated as

In an automobile assemblyplant the process that is mosttime consuming limits the pro-duction rate For examplebecause it takes longer to installthe onboard computer systemthan it takes to attach the hoodassembly the computer installa-tion is a rate-determining step

Reaction MechanismsMost chemical reactions consist of a sequence of two or more simpler reac-tions For example recent evidence indicates that the reaction 2O3 0 3O2occurs in three steps after intense ultraviolet radiation from the sun liberateschlorine atoms from certain compounds in Earthrsquos stratosphere Steps 1 and2 in this reaction may occur simultaneously or in reverse order

1 Chlorine atoms decompose ozone according to the equation Cl O3 0 O2 ClO

2 Ultraviolet radiation causes the decomposition reaction O3 0 O2 O

3 ClO produced in the reaction in step 1 reacts with O produced in step 2according to the equation ClO O 0 Cl O2

Each of the reactions described in steps 1 through 3 is called an elementarystep These three elementary steps comprise the complex reaction 2O3 0 3O2A complex reaction is one that consists of two or more elementary steps Thecomplete sequence of elementary steps that make up a complex reaction iscalled a reaction mechanism Adding the elementary steps in steps 1 through3 and canceling formulas that occur in equal amounts on both sides of the reac-tion arrow produce the net equation for the complex reaction as shown below

Elementary step Cl O3 0 O2 ClO

Elementary step O3 0 O2 O

Elementary step ClO O 0 Cl O2

Complex reaction 2O3 0 3O2

Because chlorine atoms react in step 1 of the reaction mechanism and arere-formed in step 3 chlorine is said to catalyze the decomposition of ozoneDo you know why Because ClO and O are formed in the reactions in steps1 and 2 respectively and are consumed in the reaction in step 3 they arecalled intermediates In a complex reaction an intermediate is a substanceproduced in one elementary step and consumed in a subsequent elementarystep Catalysts and intermediates do not appear in the net chemical equation

Rate-determining step You have probably heard the expression ldquoAchain is no stronger than its weakest linkrdquo Chemical reactions too have aldquoweakest linkrdquo in that a complex reaction can proceed no faster than theslowest of its elementary steps In other words the slowest elementary stepin a reaction mechanism limits the instantaneous rate of the overall reaction

For that reason the slowest of the elementary steps in a complex reaction iscalled the rate-determining step Figure 17-16 illustrates this concept in amanufacturing plant

To see how the rate-determining step affects reaction rate again considerthe gas-phase reaction between hydrogen and nitrogen monoxide discussedearlier in the chapter

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

A proposed mechanism for this reaction consists of the following elementarysteps

2NO 0 N2O2 (fast)

N2O2 H2 0 N2O H2O (slow)

N2O H2 0 N2 H2O (fast)

Although the first and third elementary steps occur relatively fast the mid-dle step is the slowest and it limits the overall reaction rate It is the rate-determining step The relative energy levels of reactants intermediatesproducts and activated complex are illustrated in Figure 17-17

Chemists can make use of instantaneous reaction rates reaction ordersand rate-determining steps to develop efficient ways to manufacture prod-ucts such as pharmaceuticals By knowing which step of the reaction is slow-est a chemist can work to speed up that rate-determining step and therebyincrease the rate of the overall reaction

The average reaction rate you learned to calculate in Section 173 givesimportant information about the reaction over a period of time Howeverchemists also may need to know at what rate the reaction is proceeding at aspecific time A pharmacist developing a new drug treatment might need toknow the progress of a reaction at an exact instant This information makesit possible to adjust the product for maximum performance Can you think ofother situations where it might be critical to know the specific reaction rateat a given time

Instantaneous Reaction RatesThe decomposition of hydrogen peroxide (H2O2) is represented as follows

2H2O2(aq) 0 2H2O(l) O2(g)

For this reaction the decrease in H2O2 concentration over time is shown inFigure 17-15 The curved line shows how the reaction rate decreases as thereaction proceeds The instantaneous rate or the rate of decomposition ata specific time can be determined by finding the slope of the straight linetangent to the curve at that instant This is because the slope of the tangentto the curve at a particular point is [H2O2]t which is one way to expressthe reaction rate In other words the rate of change in H2O2 concentrationrelates to one specific point (or instant) on the graph

Another way to determine the instantaneous rate for a chemical reactionis to use the experimentally determined rate law given the reactant concen-trations and the specific rate constant for the temperature at which the reactionoccurs For example the decomposition of dinitrogen pentoxide (N2O5) intonitrogen dioxide (NO2) and oxygen (O2) is given by the following equation

EXAMPLE PROBLEM 17-2

Calculating Instantaneous Reaction RatesThe following equation is first order in H2 and second order in NO with arate constant of 290 102 (L2(mol2middots))

2NO(g) H2(g) 0 N2O(g) H2O(g)

Calculate the instantaneous rate when the reactant concentrations are[NO] = 000200M and [H2] = 000400M

1 Analyze the ProblemThe rate law can be expressed by Rate k[NO]2[H2] Therefore the instantaneous reaction rate can be determined by insertingreactant concentrations and the specific rate constant into therate law equation

Known Unknown

[NO] 000200M Rate mol(Lmiddots)[H2] 000400Mk 290 102 (L2(mol2middots))

2 Solve for the UnknownInsert the known quantities into the rate law equation

Rate k[NO]2[H2]

Rate 290 102 (L2(mol2middots)(000200 molL)2(000400 molL))

Rate 464 106 mol(Lmiddots)

3 Evaluate the AnswerAre the units correct Units in the calculation cancel to give mol(Lmiddots)which is the common unit for the expression of reaction rates Is themagnitude reasonable A magnitude of approximately 106 mol(Lmiddots)fits with the quantities given and the rate law equation

PRACTICE PROBLEMSUse the rate law in Example Problem 17-2 and the concentrations given ineach practice problem to calculate the instantaneous rate for the reactionbetween NO and H2

24 [NO] 000500M and [H2] 000200M

25 [NO] 00100M and [H2] 000125M

26 [NO] 000446M and [H2] 000282M

The experimentally determined rate law for this reaction is

Rate k[N2O5]

where k 10 105 s1 If [N2O5] 0350M the instantaneous reactionrate would be calculated as

Reaction MechanismsMost chemical reactions consist of a sequence of two or more simpler reac-tions For example recent evidence indicates that the reaction 2O3 0 3O2occurs in three steps after intense ultraviolet radiation from the sun liberateschlorine atoms from certain compounds in Earthrsquos stratosphere Steps 1 and2 in this reaction may occur simultaneously or in reverse order

1 Chlorine atoms decompose ozone according to the equation Cl O3 0 O2 ClO

2 Ultraviolet radiation causes the decomposition reaction O3 0 O2 O

3 ClO produced in the reaction in step 1 reacts with O produced in step 2according to the equation ClO O 0 Cl O2

Each of the reactions described in steps 1 through 3 is called an elementarystep These three elementary steps comprise the complex reaction 2O3 0 3O2A complex reaction is one that consists of two or more elementary steps Thecomplete sequence of elementary steps that make up a complex reaction iscalled a reaction mechanism Adding the elementary steps in steps 1 through3 and canceling formulas that occur in equal amounts on both sides of the reac-tion arrow produce the net equation for the complex reaction as shown below

Elementary step Cl O3 0 O2 ClO

Elementary step O3 0 O2 O

Elementary step ClO O 0 Cl O2

Complex reaction 2O3 0 3O2

Because chlorine atoms react in step 1 of the reaction mechanism and arere-formed in step 3 chlorine is said to catalyze the decomposition of ozoneDo you know why Because ClO and O are formed in the reactions in steps1 and 2 respectively and are consumed in the reaction in step 3 they arecalled intermediates In a complex reaction an intermediate is a substanceproduced in one elementary step and consumed in a subsequent elementarystep Catalysts and intermediates do not appear in the net chemical equation

Rate-determining step You have probably heard the expression ldquoAchain is no stronger than its weakest linkrdquo Chemical reactions too have aldquoweakest linkrdquo in that a complex reaction can proceed no faster than theslowest of its elementary steps In other words the slowest elementary stepin a reaction mechanism limits the instantaneous rate of the overall reaction

Although the first and third elementary steps occur relatively fast the mid-dle step is the slowest and it limits the overall reaction rate It is the rate-determining step The relative energy levels of reactants intermediatesproducts and activated complex are illustrated in Figure 17-17

Chemists can make use of instantaneous reaction rates reaction ordersand rate-determining steps to develop efficient ways to manufacture prod-ucts such as pharmaceuticals By knowing which step of the reaction is slow-est a chemist can work to speed up that rate-determining step and therebyincrease the rate of the overall reaction

In many models of catalytic converters this inner structure resembles tubes in a honeycomb arrangement which provides significant surface area to accommodate the catalysts

At high temperatures (300ndash500C) on the platinum catalyst surface the dangerous carbon monoxide and hydrocarbons react with oxygen to form the compounds carbon dioxide and water

Inside the catalytic converter is a porous ceramic structure with a surface coating of platinum and rhodium particles

5 At the rhodium catalyst surface nitric oxide is converted to nitrogen and oxygen

Gasesfrom the engine and the air pass through the exhaust system to the catalytic converter Oxygen intake into the engine at this point is critical for the reactions of the catalysts

Catalytic ConverterConcerns for our environment have made a hugeimpact in the products and processes we use every dayThe catalytic converter is one of those impacts

When a combustion engine converts fuel into ener-gy the reactions of the combustion process are incom-plete Incomplete combustion results in the productionof poisonous carbon monoxide and undesirable nitro-gen oxides Since 1975 catalytic converters havereduced the exhaust emissions that contribute to airpollution by approximately 90

The average reaction rate you learned to calculate in Section 173 givesimportant information about the reaction over a period of time Howeverchemists also may need to know at what rate the reaction is proceeding at aspecific time A pharmacist developing a new drug treatment might need toknow the progress of a reaction at an exact instant This information makesit possible to adjust the product for maximum performance Can you think ofother situations where it might be critical to know the specific reaction rateat a given time

Instantaneous Reaction RatesThe decomposition of hydrogen peroxide (H2O2) is represented as follows

2H2O2(aq) 0 2H2O(l) O2(g)

For this reaction the decrease in H2O2 concentration over time is shown inFigure 17-15 The curved line shows how the reaction rate decreases as thereaction proceeds The instantaneous rate or the rate of decomposition ata specific time can be determined by finding the slope of the straight linetangent to the curve at that instant This is because the slope of the tangentto the curve at a particular point is [H2O2]t which is one way to expressthe reaction rate In other words the rate of change in H2O2 concentrationrelates to one specific point (or instant) on the graph

Another way to determine the instantaneous rate for a chemical reactionis to use the experimentally determined rate law given the reactant concen-trations and the specific rate constant for the temperature at which the reactionoccurs For example the decomposition of dinitrogen pentoxide (N2O5) intonitrogen dioxide (NO2) and oxygen (O2) is given by the following equation

EXAMPLE PROBLEM 17-2

Calculating Instantaneous Reaction RatesThe following equation is first order in H2 and second order in NO with arate constant of 290 102 (L2(mol2middots))

2NO(g) H2(g) 0 N2O(g) H2O(g)

Calculate the instantaneous rate when the reactant concentrations are[NO] = 000200M and [H2] = 000400M

1 Analyze the ProblemThe rate law can be expressed by Rate k[NO]2[H2] Therefore the instantaneous reaction rate can be determined by insertingreactant concentrations and the specific rate constant into therate law equation

Known Unknown

[NO] 000200M Rate mol(Lmiddots)[H2] 000400Mk 290 102 (L2(mol2middots))

2 Solve for the UnknownInsert the known quantities into the rate law equation

Rate k[NO]2[H2]

Rate 290 102 (L2(mol2middots)(000200 molL)2(000400 molL))

Rate 464 106 mol(Lmiddots)

3 Evaluate the AnswerAre the units correct Units in the calculation cancel to give mol(Lmiddots)which is the common unit for the expression of reaction rates Is themagnitude reasonable A magnitude of approximately 106 mol(Lmiddots)fits with the quantities given and the rate law equation

PRACTICE PROBLEMSUse the rate law in Example Problem 17-2 and the concentrations given ineach practice problem to calculate the instantaneous rate for the reactionbetween NO and H2

24 [NO] 000500M and [H2] 000200M

25 [NO] 00100M and [H2] 000125M

26 [NO] 000446M and [H2] 000282M

The experimentally determined rate law for this reaction is

Rate k[N2O5]

where k 10 105 s1 If [N2O5] 0350M the instantaneous reactionrate would be calculated as

Rate (10 105 s1)(0350 molL)

In an automobile assemblyplant the process that is mosttime consuming limits the pro-duction rate For examplebecause it takes longer to installthe onboard computer systemthan it takes to attach the hoodassembly the computer installa-tion is a rate-determining step

Reaction MechanismsMost chemical reactions consist of a sequence of two or more simpler reac-tions For example recent evidence indicates that the reaction 2O3 0 3O2occurs in three steps after intense ultraviolet radiation from the sun liberateschlorine atoms from certain compounds in Earthrsquos stratosphere Steps 1 and2 in this reaction may occur simultaneously or in reverse order

1 Chlorine atoms decompose ozone according to the equation Cl O3 0 O2 ClO

2 Ultraviolet radiation causes the decomposition reaction O3 0 O2 O

3 ClO produced in the reaction in step 1 reacts with O produced in step 2according to the equation ClO O 0 Cl O2

Each of the reactions described in steps 1 through 3 is called an elementarystep These three elementary steps comprise the complex reaction 2O3 0 3O2A complex reaction is one that consists of two or more elementary steps Thecomplete sequence of elementary steps that make up a complex reaction iscalled a reaction mechanism Adding the elementary steps in steps 1 through3 and canceling formulas that occur in equal amounts on both sides of the reac-tion arrow produce the net equation for the complex reaction as shown below

Elementary step Cl O3 0 O2 ClO

Elementary step O3 0 O2 O

Elementary step ClO O 0 Cl O2

Complex reaction 2O3 0 3O2

Because chlorine atoms react in step 1 of the reaction mechanism and arere-formed in step 3 chlorine is said to catalyze the decomposition of ozoneDo you know why Because ClO and O are formed in the reactions in steps1 and 2 respectively and are consumed in the reaction in step 3 they arecalled intermediates In a complex reaction an intermediate is a substanceproduced in one elementary step and consumed in a subsequent elementarystep Catalysts and intermediates do not appear in the net chemical equation

Rate-determining step You have probably heard the expression ldquoAchain is no stronger than its weakest linkrdquo Chemical reactions too have aldquoweakest linkrdquo in that a complex reaction can proceed no faster than theslowest of its elementary steps In other words the slowest elementary stepin a reaction mechanism limits the instantaneous rate of the overall reaction

For that reason the slowest of the elementary steps in a complex reaction iscalled the rate-determining step Figure 17-16 illustrates this concept in amanufacturing plant

To see how the rate-determining step affects reaction rate again considerthe gas-phase reaction between hydrogen and nitrogen monoxide discussedearlier in the chapter

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

A proposed mechanism for this reaction consists of the following elementarysteps

2NO 0 N2O2 (fast)

N2O2 H2 0 N2O H2O (slow)

N2O H2 0 N2 H2O (fast)

Although the first and third elementary steps occur relatively fast the mid-dle step is the slowest and it limits the overall reaction rate It is the rate-determining step The relative energy levels of reactants intermediatesproducts and activated complex are illustrated in Figure 17-17

Chemists can make use of instantaneous reaction rates reaction ordersand rate-determining steps to develop efficient ways to manufacture prod-ucts such as pharmaceuticals By knowing which step of the reaction is slow-est a chemist can work to speed up that rate-determining step and therebyincrease the rate of the overall reaction

In many models of catalytic converters this inner structure resembles tubes in a honeycomb arrangement which provides significant surface area to accommodate the catalysts

At high temperatures (300ndash500C) on the platinum catalyst surface the dangerous carbon monoxide and hydrocarbons react with oxygen to form the compounds carbon dioxide and water

Inside the catalytic converter is a porous ceramic structure with a surface coating of platinum and rhodium particles

5 At the rhodium catalyst surface nitric oxide is converted to nitrogen and oxygen

Gasesfrom the engine and the air pass through the exhaust system to the catalytic converter Oxygen intake into the engine at this point is critical for the reactions of the catalysts

Catalytic ConverterConcerns for our environment have made a hugeimpact in the products and processes we use every dayThe catalytic converter is one of those impacts

When a combustion engine converts fuel into ener-gy the reactions of the combustion process are incom-plete Incomplete combustion results in the productionof poisonous carbon monoxide and undesirable nitro-gen oxides Since 1975 catalytic converters havereduced the exhaust emissions that contribute to airpollution by approximately 90

Key Equations and Relationships

Summary171 A Model for Reaction Ratesbull The rate of a chemical reaction is expressed as the

rate at which a reactant is consumed or the rate atwhich a product is formed

bull Reaction rates are generally calculated and expressedin moles per liter per second (mol(Lmiddots))

bull In order to react the particles in a chemical reactionmust collide in a correct orientation and with suffi-cient energy to form the activated complex

bull The rate of a chemical reaction is unrelated to thespontaneity of the reaction

172 Factors Affecting Reaction Ratesbull Key factors that influence the rate of chemical reac-

tions include reactivity concentration surface areatemperature and catalysts

bull Catalysts increase the rates of chemical reactions bylowering activation energies

bull Raising the temperature of a reaction increases therate of the reaction by increasing the collision fre-quency and the number of collisions forming theactivated complex

173 Reaction Rate Lawsbull The mathematical relationship between the rate of a

chemical reaction at a given temperature and theconcentrations of reactants is called the rate law

bull The rate law for a chemical reaction is determinedexperimentally using the method of initial rates

174 Instantaneous Reaction Rates andReaction Mechanisms

bull The instantaneous rate for a chemical reaction iscalculated from the rate law the specific rate con-stant and the concentrations of all reactants

bull Most chemical reactions are complex reactions con-sisting of two or more elementary steps

bull A reaction mechanism is the complete sequence ofelementary steps that make up a complex reaction

bull For a complex reaction the rate-determining steplimits the instantaneous rate of the overall reaction

EXAMPLE PROBLEM 17-2

Calculating Instantaneous Reaction RatesThe following equation is first order in H2 and second order in NO with arate constant of 290 102 (L2(mol2middots))

2NO(g) H2(g) 0 N2O(g) H2O(g)

Calculate the instantaneous rate when the reactant concentrations are[NO] = 000200M and [H2] = 000400M

1 Analyze the ProblemThe rate law can be expressed by Rate k[NO]2[H2] Therefore the instantaneous reaction rate can be determined by insertingreactant concentrations and the specific rate constant into therate law equation

Known Unknown

[NO] 000200M Rate mol(Lmiddots)[H2] 000400Mk 290 102 (L2(mol2middots))

2 Solve for the UnknownInsert the known quantities into the rate law equation

Rate k[NO]2[H2]

Rate 290 102 (L2(mol2middots)(000200 molL)2(000400 molL))

Rate 464 106 mol(Lmiddots)

3 Evaluate the AnswerAre the units correct Units in the calculation cancel to give mol(Lmiddots)which is the common unit for the expression of reaction rates Is themagnitude reasonable A magnitude of approximately 106 mol(Lmiddots)fits with the quantities given and the rate law equation

PRACTICE PROBLEMSUse the rate law in Example Problem 17-2 and the concentrations given ineach practice problem to calculate the instantaneous rate for the reactionbetween NO and H2

24 [NO] 000500M and [H2] 000200M

25 [NO] 00100M and [H2] 000125M

26 [NO] 000446M and [H2] 000282M

The experimentally determined rate law for this reaction is

Rate k[N2O5]

where k 10 105 s1 If [N2O5] 0350M the instantaneous reactionrate would be calculated as

Rate (10 105 s1)(0350 molL)

In an automobile assemblyplant the process that is mosttime consuming limits the pro-duction rate For examplebecause it takes longer to installthe onboard computer systemthan it takes to attach the hoodassembly the computer installa-tion is a rate-determining step

Reaction MechanismsMost chemical reactions consist of a sequence of two or more simpler reac-tions For example recent evidence indicates that the reaction 2O3 0 3O2occurs in three steps after intense ultraviolet radiation from the sun liberateschlorine atoms from certain compounds in Earthrsquos stratosphere Steps 1 and2 in this reaction may occur simultaneously or in reverse order

1 Chlorine atoms decompose ozone according to the equation Cl O3 0 O2 ClO

2 Ultraviolet radiation causes the decomposition reaction O3 0 O2 O

3 ClO produced in the reaction in step 1 reacts with O produced in step 2according to the equation ClO O 0 Cl O2

Each of the reactions described in steps 1 through 3 is called an elementarystep These three elementary steps comprise the complex reaction 2O3 0 3O2A complex reaction is one that consists of two or more elementary steps Thecomplete sequence of elementary steps that make up a complex reaction iscalled a reaction mechanism Adding the elementary steps in steps 1 through3 and canceling formulas that occur in equal amounts on both sides of the reac-tion arrow produce the net equation for the complex reaction as shown below

Elementary step Cl O3 0 O2 ClO

Elementary step O3 0 O2 O

Elementary step ClO O 0 Cl O2

Complex reaction 2O3 0 3O2

Because chlorine atoms react in step 1 of the reaction mechanism and arere-formed in step 3 chlorine is said to catalyze the decomposition of ozoneDo you know why Because ClO and O are formed in the reactions in steps1 and 2 respectively and are consumed in the reaction in step 3 they arecalled intermediates In a complex reaction an intermediate is a substanceproduced in one elementary step and consumed in a subsequent elementarystep Catalysts and intermediates do not appear in the net chemical equation

Rate-determining step You have probably heard the expression ldquoAchain is no stronger than its weakest linkrdquo Chemical reactions too have aldquoweakest linkrdquo in that a complex reaction can proceed no faster than theslowest of its elementary steps In other words the slowest elementary stepin a reaction mechanism limits the instantaneous rate of the overall reaction

For that reason the slowest of the elementary steps in a complex reaction iscalled the rate-determining step Figure 17-16 illustrates this concept in amanufacturing plant

To see how the rate-determining step affects reaction rate again considerthe gas-phase reaction between hydrogen and nitrogen monoxide discussedearlier in the chapter

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

A proposed mechanism for this reaction consists of the following elementarysteps

2NO 0 N2O2 (fast)

N2O2 H2 0 N2O H2O (slow)

N2O H2 0 N2 H2O (fast)

Although the first and third elementary steps occur relatively fast the mid-dle step is the slowest and it limits the overall reaction rate It is the rate-determining step The relative energy levels of reactants intermediatesproducts and activated complex are illustrated in Figure 17-17

Chemists can make use of instantaneous reaction rates reaction ordersand rate-determining steps to develop efficient ways to manufacture prod-ucts such as pharmaceuticals By knowing which step of the reaction is slow-est a chemist can work to speed up that rate-determining step and therebyincrease the rate of the overall reaction

rate at which a reactant is consumed or the rate atwhich a product is formed

bull Reaction rates are generally calculated and expressedin moles per liter per second (mol(Lmiddots))

bull In order to react the particles in a chemical reactionmust collide in a correct orientation and with suffi-cient energy to form the activated complex

bull The rate of a chemical reaction is unrelated to thespontaneity of the reaction

In an automobile assemblyplant the process that is mosttime consuming limits the pro-duction rate For examplebecause it takes longer to installthe onboard computer systemthan it takes to attach the hoodassembly the computer installa-tion is a rate-determining step

Reaction MechanismsMost chemical reactions consist of a sequence of two or more simpler reac-tions For example recent evidence indicates that the reaction 2O3 0 3O2occurs in three steps after intense ultraviolet radiation from the sun liberateschlorine atoms from certain compounds in Earthrsquos stratosphere Steps 1 and2 in this reaction may occur simultaneously or in reverse order

1 Chlorine atoms decompose ozone according to the equation Cl O3 0 O2 ClO

2 Ultraviolet radiation causes the decomposition reaction O3 0 O2 O

3 ClO produced in the reaction in step 1 reacts with O produced in step 2according to the equation ClO O 0 Cl O2

Each of the reactions described in steps 1 through 3 is called an elementarystep These three elementary steps comprise the complex reaction 2O3 0 3O2A complex reaction is one that consists of two or more elementary steps Thecomplete sequence of elementary steps that make up a complex reaction iscalled a reaction mechanism Adding the elementary steps in steps 1 through3 and canceling formulas that occur in equal amounts on both sides of the reac-tion arrow produce the net equation for the complex reaction as shown below

Elementary step Cl O3 0 O2 ClO

Elementary step O3 0 O2 O

Elementary step ClO O 0 Cl O2

Complex reaction 2O3 0 3O2

Because chlorine atoms react in step 1 of the reaction mechanism and arere-formed in step 3 chlorine is said to catalyze the decomposition of ozoneDo you know why Because ClO and O are formed in the reactions in steps1 and 2 respectively and are consumed in the reaction in step 3 they arecalled intermediates In a complex reaction an intermediate is a substanceproduced in one elementary step and consumed in a subsequent elementarystep Catalysts and intermediates do not appear in the net chemical equation

Rate-determining step You have probably heard the expression ldquoAchain is no stronger than its weakest linkrdquo Chemical reactions too have aldquoweakest linkrdquo in that a complex reaction can proceed no faster than theslowest of its elementary steps In other words the slowest elementary stepin a reaction mechanism limits the instantaneous rate of the overall reaction

For that reason the slowest of the elementary steps in a complex reaction iscalled the rate-determining step Figure 17-16 illustrates this concept in amanufacturing plant

To see how the rate-determining step affects reaction rate again considerthe gas-phase reaction between hydrogen and nitrogen monoxide discussedearlier in the chapter

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

A proposed mechanism for this reaction consists of the following elementarysteps

2NO 0 N2O2 (fast)

N2O2 H2 0 N2O H2O (slow)

N2O H2 0 N2 H2O (fast)

Although the first and third elementary steps occur relatively fast the mid-dle step is the slowest and it limits the overall reaction rate It is the rate-determining step The relative energy levels of reactants intermediatesproducts and activated complex are illustrated in Figure 17-17

Chemists can make use of instantaneous reaction rates reaction ordersand rate-determining steps to develop efficient ways to manufacture prod-ucts such as pharmaceuticals By knowing which step of the reaction is slow-est a chemist can work to speed up that rate-determining step and therebyincrease the rate of the overall reaction

For that reason the slowest of the elementary steps in a complex reaction iscalled the rate-determining step Figure 17-16 illustrates this concept in amanufacturing plant

To see how the rate-determining step affects reaction rate again considerthe gas-phase reaction between hydrogen and nitrogen monoxide discussedearlier in the chapter

2NO(g) 2H2(g) 0 N2(g) 2H2O(g)

A proposed mechanism for this reaction consists of the following elementarysteps

2NO 0 N2O2 (fast)

N2O2 H2 0 N2O H2O (slow)

N2O H2 0 N2 H2O (fast)

Although the first and third elementary steps occur relatively fast the mid-dle step is the slowest and it limits the overall reaction rate It is the rate-determining step The relative energy levels of reactants intermediatesproducts and activated complex are illustrated in Figure 17-17

Chemists can make use of instantaneous reaction rates reaction ordersand rate-determining steps to develop efficient ways to manufacture prod-ucts such as pharmaceuticals By knowing which step of the reaction is slow-est a chemist can work to speed up that rate-determining step and therebyincrease the rate of the overall reaction

In many models of catalytic converters this inner structure resembles tubes in a honeycomb arrangement which provides significant surface area to accommodate the catalysts

At high temperatures (300ndash500C) on the platinum catalyst surface the dangerous carbon monoxide and hydrocarbons react with oxygen to form the compounds carbon dioxide and water

Inside the catalytic converter is a porous ceramic structure with a surface coating of platinum and rhodium particles

5 At the rhodium catalyst surface nitric oxide is converted to nitrogen and oxygen

Gasesfrom the engine and the air pass through the exhaust system to the catalytic converter Oxygen intake into the engine at this point is critical for the reactions of the catalysts

Catalytic ConverterConcerns for our environment have made a hugeimpact in the products and processes we use every dayThe catalytic converter is one of those impacts

When a combustion engine converts fuel into ener-gy the reactions of the combustion process are incom-plete Incomplete combustion results in the productionof poisonous carbon monoxide and undesirable nitro-gen oxides Since 1975 catalytic converters havereduced the exhaust emissions that contribute to airpollution by approximately 90

Key Equations and Relationships

Summary171 A Model for Reaction Ratesbull The rate of a chemical reaction is expressed as the

rate at which a reactant is consumed or the rate atwhich a product is formed

bull Reaction rates are generally calculated and expressedin moles per liter per second (mol(Lmiddots))

bull In order to react the particles in a chemical reactionmust collide in a correct orientation and with suffi-cient energy to form the activated complex

bull The rate of a chemical reaction is unrelated to thespontaneity of the reaction

172 Factors Affecting Reaction Ratesbull Key factors that influence the rate of chemical reac-

tions include reactivity concentration surface areatemperature and catalysts

bull Catalysts increase the rates of chemical reactions bylowering activation energies

bull Raising the temperature of a reaction increases therate of the reaction by increasing the collision fre-quency and the number of collisions forming theactivated complex

173 Reaction Rate Lawsbull The mathematical relationship between the rate of a

chemical reaction at a given temperature and theconcentrations of reactants is called the rate law

bull The rate law for a chemical reaction is determinedexperimentally using the method of initial rates

174 Instantaneous Reaction Rates andReaction Mechanisms

bull The instantaneous rate for a chemical reaction iscalculated from the rate law the specific rate con-stant and the concentrations of all reactants

bull Most chemical reactions are complex reactions con-sisting of two or more elementary steps

bull A reaction mechanism is the complete sequence ofelementary steps that make up a complex reaction

bull For a complex reaction the rate-determining steplimits the instantaneous rate of the overall reaction

In many models of catalytic converters this inner structure resembles tubes in a honeycomb arrangement which provides significant surface area to accommodate the catalysts

At high temperatures (300ndash500C) on the platinum catalyst surface the dangerous carbon monoxide and hydrocarbons react with oxygen to form the compounds carbon dioxide and water

Inside the catalytic converter is a porous ceramic structure with a surface coating of platinum and rhodium particles

Gasesfrom the engine and the air pass through the exhaust system to the catalytic converter Oxygen intake into the engine at this point is critical for the reactions of the catalysts

Catalytic ConverterConcerns for our environment have made a hugeimpact in the products and processes we use every dayThe catalytic converter is one of those impacts

When a combustion engine converts fuel into ener-gy the reactions of the combustion process are incom-plete Incomplete combustion results in the productionof poisonous carbon monoxide and undesirable nitro-gen oxides Since 1975 catalytic converters havereduced the exhaust emissions that contribute to airpollution by approximately 90

Key Equations and Relationships

Summary171 A Model for Reaction Ratesbull The rate of a chemical reaction is expressed as the

rate at which a reactant is consumed or the rate atwhich a product is formed

bull Reaction rates are generally calculated and expressedin moles per liter per second (mol(Lmiddots))

bull In order to react the particles in a chemical reactionmust collide in a correct orientation and with suffi-cient energy to form the activated complex

bull The rate of a chemical reaction is unrelated to thespontaneity of the reaction

172 Factors Affecting Reaction Ratesbull Key factors that influence the rate of chemical reac-

tions include reactivity concentration surface areatemperature and catalysts

bull Catalysts increase the rates of chemical reactions bylowering activation energies

bull Raising the temperature of a reaction increases therate of the reaction by increasing the collision fre-quency and the number of collisions forming theactivated complex

173 Reaction Rate Lawsbull The mathematical relationship between the rate of a

chemical reaction at a given temperature and theconcentrations of reactants is called the rate law

bull The rate law for a chemical reaction is determinedexperimentally using the method of initial rates

174 Instantaneous Reaction Rates andReaction Mechanisms

bull The instantaneous rate for a chemical reaction iscalculated from the rate law the specific rate con-stant and the concentrations of all reactants

bull Most chemical reactions are complex reactions con-sisting of two or more elementary steps

bull A reaction mechanism is the complete sequence ofelementary steps that make up a complex reaction

bull For a complex reaction the rate-determining steplimits the instantaneous rate of the overall reaction

In many models of catalytic converters this inner structure resembles tubes in a honeycomb arrangement which provides significant surface area to accommodate the catalysts

At high temperatures (300ndash500C) on the platinum catalyst surface the dangerous carbon monoxide and hydrocarbons react with oxygen to form the compounds carbon dioxide and water

Inside the catalytic converter is a porous ceramic structure with a surface coating of platinum and rhodium particles

5 At the rhodium catalyst surface nitric oxide is converted to nitrogen and oxygen

Gasesfrom the engine and the air pass through the exhaust system to the catalytic converter Oxygen intake into the engine at this point is critical for the reactions of the catalysts

Catalytic ConverterConcerns for our environment have made a hugeimpact in the products and processes we use every dayThe catalytic converter is one of those impacts

When a combustion engine converts fuel into ener-gy the reactions of the combustion process are incom-plete Incomplete combustion results in the productionof poisonous carbon monoxide and undesirable nitro-gen oxides Since 1975 catalytic converters havereduced the exhaust emissions that contribute to airpollution by approximately 90

Key Equations and Relationships

Summary171 A Model for Reaction Ratesbull The rate of a chemical reaction is expressed as the

rate at which a reactant is consumed or the rate atwhich a product is formed

bull Reaction rates are generally calculated and expressedin moles per liter per second (mol(Lmiddots))

bull In order to react the particles in a chemical reactionmust collide in a correct orientation and with suffi-cient energy to form the activated complex

bull The rate of a chemical reaction is unrelated to thespontaneity of the reaction

172 Factors Affecting Reaction Ratesbull Key factors that influence the rate of chemical reac-

tions include reactivity concentration surface areatemperature and catalysts

bull Catalysts increase the rates of chemical reactions bylowering activation energies

bull Raising the temperature of a reaction increases therate of the reaction by increasing the collision fre-quency and the number of collisions forming theactivated complex

173 Reaction Rate Lawsbull The mathematical relationship between the rate of a

chemical reaction at a given temperature and theconcentrations of reactants is called the rate law

bull The rate law for a chemical reaction is determinedexperimentally using the method of initial rates

174 Instantaneous Reaction Rates andReaction Mechanisms

bull The instantaneous rate for a chemical reaction iscalculated from the rate law the specific rate con-stant and the concentrations of all reactants

bull Most chemical reactions are complex reactions con-sisting of two or more elementary steps

bull A reaction mechanism is the complete sequence ofelementary steps that make up a complex reaction

bull For a complex reaction the rate-determining steplimits the instantaneous rate of the overall reaction

In many models of catalytic converters this inner structure resembles tubes in a honeycomb arrangement which provides significant surface area to accommodate the catalysts

At high temperatures (300ndash500C) on the platinum catalyst surface the dangerous carbon monoxide and hydrocarbons react with oxygen to form the compounds carbon dioxide and water

Inside the catalytic converter is a porous ceramic structure with a surface coating of platinum and rhodium particles

5 At the rhodium catalyst surface nitric oxide is converted to nitrogen and oxygen

Gasesfrom the engine and the air pass through the exhaust system to the catalytic converter Oxygen intake into the engine at this point is critical for the reactions of the catalysts

Catalytic ConverterConcerns for our environment have made a hugeimpact in the products and processes we use every dayThe catalytic converter is one of those impacts

When a combustion engine converts fuel into ener-gy the reactions of the combustion process are incom-plete Incomplete combustion results in the productionof poisonous carbon monoxide and undesirable nitro-gen oxides Since 1975 catalytic converters havereduced the exhaust emissions that contribute to airpollution by approximately 90

Key Equations and Relationships

Summary171 A Model for Reaction Ratesbull The rate of a chemical reaction is expressed as the

rate at which a reactant is consumed or the rate atwhich a product is formed

bull Reaction rates are generally calculated and expressedin moles per liter per second (mol(Lmiddots))

bull In order to react the particles in a chemical reactionmust collide in a correct orientation and with suffi-cient energy to form the activated complex

bull The rate of a chemical reaction is unrelated to thespontaneity of the reaction

172 Factors Affecting Reaction Ratesbull Key factors that influence the rate of chemical reac-

tions include reactivity concentration surface areatemperature and catalysts

bull Catalysts increase the rates of chemical reactions bylowering activation energies

bull Raising the temperature of a reaction increases therate of the reaction by increasing the collision fre-quency and the number of collisions forming theactivated complex

173 Reaction Rate Lawsbull The mathematical relationship between the rate of a

chemical reaction at a given temperature and theconcentrations of reactants is called the rate law

bull The rate law for a chemical reaction is determinedexperimentally using the method of initial rates

174 Instantaneous Reaction Rates andReaction Mechanisms

bull The instantaneous rate for a chemical reaction iscalculated from the rate law the specific rate con-stant and the concentrations of all reactants

bull Most chemical reactions are complex reactions con-sisting of two or more elementary steps

bull A reaction mechanism is the complete sequence ofelementary steps that make up a complex reaction

Key Equations and Relationships

Summary171 A Model for Reaction Ratesbull The rate of a chemical reaction is expressed as the

rate at which a reactant is consumed or the rate atwhich a product is formed

bull Reaction rates are generally calculated and expressedin moles per liter per second (mol(Lmiddots))

bull In order to react the particles in a chemical reactionmust collide in a correct orientation and with suffi-cient energy to form the activated complex

bull The rate of a chemical reaction is unrelated to thespontaneity of the reaction

172 Factors Affecting Reaction Ratesbull Key factors that influence the rate of chemical reac-

tions include reactivity concentration surface areatemperature and catalysts

bull Catalysts increase the rates of chemical reactions bylowering activation energies

bull Raising the temperature of a reaction increases therate of the reaction by increasing the collision fre-quency and the number of collisions forming theactivated complex

173 Reaction Rate Lawsbull The mathematical relationship between the rate of a

chemical reaction at a given temperature and theconcentrations of reactants is called the rate law

bull The rate law for a chemical reaction is determinedexperimentally using the method of initial rates

174 Instantaneous Reaction Rates andReaction Mechanisms

bull The instantaneous rate for a chemical reaction iscalculated from the rate law the specific rate con-stant and the concentrations of all reactants

bull Most chemical reactions are complex reactions con-sisting of two or more elementary steps

bull A reaction mechanism is the complete sequence ofelementary steps that make up a complex reaction

bull For a complex reaction the rate-determining steplimits the instantaneous rate of the overall reaction
