2 Reaction Mechanisms 7. Elementary Reactions 8. The Rate Law and the Mechanisms 9. Catalysis Reaction Mechanisms A balanced chemical equation is a description of the overall result of a chemical reaction. However, what actually happens on a molecular level may be more involved than is represented by this single equation. The reaction may take place in several steps. Each step, called an elementary reaction , is a single molecular event. The set of elementary reactions who overall effect is given by the balanced chemical equation is called the reaction mechanism . A reaction intermediate is a species produced during a reaction that does not appear in the net equation because it reacts in a subsequent step in the mechanism. For example, consider the reaction:
