Lesson 29 Reaction mechanisms A reaction mechanism is a step-by-step description of a chemical reaction at molecular level Each step in a mechanism is called an elementary reaction Reaction mechanisms must agree with the overall stoichiometric equation for the reaction Reaction mechanism should agree with the experimentally determined rate laws for the reaction Reaction mechanisms are proposed based on experimental data – It is very difficult, if not impossible, to infer a reaction mechanism from the overall chemical equation alone

Lesson 29 Elementary reactions Elementary reactions are classified as: Unimolecular: A → products (dissociation) Bimolecular: A + B → products (bimolecular collision) Termolecular: A + B + C → products (very rare) For elementary reactions, the order of the reaction with respect to a given reagent equals the stoichiometric coefficient of the reagent: aA + bB → products r = k [ A ] a [ B ] b
