| Question | Answer |
|---|---|
| the step-by-step sequence of reactions by which the overall chemical change occurs | reaction mechanism |
| species that appear in some steps but not in the net equation | intermediate |
| reaction in whose reactants and products exist in a single phase | homogeneous reaction |
| set of assumptions regarding collisions and reactions | collision theory |
| the minimum energy required to transform the reactants into an activated complex | activation energy |
| a transitional structure that results from an effective collision and that persists while old bonds are breaking and new bonds are forming | activated complex |
| the change in the concentration of reactants per unit of time as the reaction proceeds | reaction rate |
| the area of chemistry that is concerned with reaction rates and reaction mechanisms | chemical kinetics |
| involve reactants in two different phases | heterogeneous reaction |
| a substance that changes the rate of a chemical reaction without itself being permanently consumed | catalyst |
| the action of a catalyst | catalysis |
| a catalyst that is in the same phase as all the reactants and products in a reaction system | homogeneous catalyst |
| a catalyst that is phase different from that of the reactants | heterogeneous catalyst |
| the slowest-rate step for a chemical reaction | rate-determining step |
