| Term | Definition |
|---|
| activated complex | a molecule in an unstable state intermediate to the reactants and the products in the chemical reaction |
| activation energy | the minimum amount of energy required to start a chemical reaction |
| catalysis | the acceleration of a chemical reaction by a catalyst |
| catalyst | a substance that changes the rate of a chemical reaction without being consumed or changed significantly |
| chemical kinetics | the area of chemistry that is the study of reaction rates and reaction mechanisms |
| heterogeneous catalyst | a catalyst that is in a different phase from the phase of the reactants |
| heterogeneous reaction | heterogeneous reaction |
| heterogeneous reaction | heterogeneous reaction |
| heterogeneous reaction | heterogeneous reaction |
| intermediate | a substance that forms in a middle stage of a chemical reaction and is considered a stepping stone between the parent substance and the final product |
| order | in chemistry, a classification of chemical reactions that depends on the number of molecules that appear to enter into the reaction |
| rate law | the expression that shows how the rate of formation of product depends on the concentration of all species other than the solvent that take part in a reaction |
| rate-determining step | in a multistep chemical reaction, the step that has the lowest velocity, which determines the rate of the overall reaction |
| reaction mechanism | the way in which a chemical reaction takes place; expressed in a series of chemical equations |
| reaction rate | the rate at which a chemical reaction takes place; measured by the rate of formation of the product or the rate of disappearance of the reactants |
