When an equilibrium is When an equilibrium is disrupted, the reaction will disrupted, the reaction will shift to restore equilibrium. shift to restore equilibrium.

The equilibrium can be affected by:The equilibrium can be affected by:

- adding substances – the - adding substances – the reaction will shift away from the reaction will shift away from the change.change.

- removing substances – the - removing substances – the reaction will shift toward the reaction will shift toward the change.change.

- temperature – acts like - temperature – acts like a reactant/producta reactant/product

- container size – smaller - container size – smaller container will shift toward container will shift toward small number of moleculessmall number of molecules

- Adding inert gasses – no - Adding inert gasses – no effecteffect

For example: Consider the For example: Consider the reactionreaction

A + B A + B C C H = -453 H = -453 kJ/molkJ/mol

1) If pressure of A is increased1) If pressure of A is increased

A + B A + B C C H = -453 kJ/molH = -453 kJ/mol

1)1) If pressure of A is increasedIf pressure of A is increased

Reaction will shift rightReaction will shift right

2) 2) The temperature of the The temperature of the reaction is increased reaction is increased

Reaction will shift leftReaction will shift left

3) 3) A catalyst is added to the A catalyst is added to the system system

For example: Consider the reactionFor example: Consider the reaction

3) 3) A catalyst is added to the system A catalyst is added to the system

No change in the equilibriumNo change in the equilibrium

4) 4) More compound B is steadily More compound B is steadily added to the reaction chamberadded to the reaction chamber

4)4) More compound B is steadily More compound B is steadily added to the reaction chamberadded to the reaction chamber

The reaction will shift rightThe reaction will shift right

5) 5) An inhibitor is added An inhibitor is added

5)5) An inhibitor is addedAn inhibitor is added

No shift in equilibrium No shift in equilibrium

6) 6) Argon gas is added to the Argon gas is added to the reaction chamber reaction chamber

6)6) Argon gas is added to the Argon gas is added to the reaction chamber reaction chamber

No shift in equilibriumNo shift in equilibrium

7) 7) The container is made The container is made smaller smaller
