| A | B |
|---|
| kinetics | the study of the rate of reactions and the steps by which they occur |
| collision theory | molecules must undergo forceful, properly oriented collsions for a reaction to occur |
| activation energy | minimum amount of kinetic energy that colliding molecules must possess to react |
| activated complex | theoretical transition structure between reactants and products |
| reaction rate | the speed at which reactants disappear or products appear |
| heterogeneous reaction | a reaction in which the reactants are in different phases |
| catalyst | a substance that changes a reaction rate without being permanently changed or consumed by the reaction |
| homogeneous catalyst | a catalyst in the same phase as the reactants or in solution with a reactant |
| heterogeneous catalyst | a catalyst in a separate phase from the reactants |
| enzyme | biological catalyst |
| inhibitor | a substance that binds to and reduces the effect of a catalyst |
| reaction mechanism | the series of steps that make up a reaction |
| elementary step | one of a series of steps in a reaction mechanism |
| rate-determining step | the slowest elementary step in a reaction |
| complex reaction | a reaction made up of multiple elementary steps |
| intermediate | a substance formed in one step and used up in the next step |
| homogeneous reaction | a reaction in which all the reactants and products are in the same phase |
| reaction order | an indicator of how the rate of a reaction is affected by that specific reactant's concentration |
| rate law | an equation that mathematically describes how fast a reaction can occur |
| specific rate constant | the experimentally determined rate for an individual reaction under specified conditions |
| pharmacokinetics | the study of how the human body processes medication |
| adsorption | the collection of one substance on the surface of another |
