The enthalpy change, delta H,For the breaking of a particularBond in a mole of gaseous substance

Bond enthalpy

The quantitative measure of themagnitude of a dipole is called?

Dipole moment

The dipole moment due only to The two atoms in that bond

Bond Dipole

Define Polar Molecule

A molecule such as HF in which the centers of positive and negative charge do not coincide

Define electron-domain geometry.

The arrangement of electron domains about the central atom of an ABn molecule

The time required for the concentrationOf a reactant to drop to one half its initial value

Half-Life

Define VSEPR and state what itStands for

A model that accounts for the geometric arrangements of shared and unshared electron pairs around a central atom in terms of the repulsions between electron pairs(Valence-shell electron-pair repulsion)

A solid whose atoms, ions, orMolecules are ordered inWell-defined arrangements

Crystalline solid

The highest temperature at whichA substance can exist as a liquid

Critical temperature

Define Amorphous solid

A solid whose particles have no orderly structure, they lack well-defined faces and shapes.

A process that is capable of proceedingin a given direction, as written or described, without needing to be drivenby an outside source of energy.

Spontaneous Process

Define Collision model

A theory based on the idea that molecules must collide to react; it explains the factors influencing reaction rates in terms of frequency of collisions, the number of collisions with energies exceeding the activation energy, and the probability that the collisions occur with suitable orientations.

The law that expresses the notion that there is an inherent direction in which processes occur

Second Law of Thermodynamics

A reaction whose rate depends on theReactant concentration raised to thesecond power or on the concentrationsof two different reactants, each raised to the first power

Second-order Reaction

Define irreversible process

A process that cannot be simply reversed to restore the system to its original state
