WebSep 27, 2014 · The molecularity of a reaction is defined as the number of molecules or ions that participate in the rate determining step. A mechanism in which two reacting species combine in the transition state of the rate-determining step is called bimolecular. If a single species makes up the transition state, the reaction would be called unimolecular. WebJan 24, 2024 · Molecularity applies to single elementary reaction steps and is seldom higher than 2. The reaction order is the "effective molecularity" of the whole set of linked reactions, if it had been a single step reaction. It need not to be integer and has just indirect relation to molecularities of elementary steps.

The molecularity of a reaction is

WebAn "elementary reaction" is a chemical reaction in which one or more of the chemical species react directly to form products in a single reaction step and with a single transition state. In an elementary reaction stoichiometry coefficients of reactants are order with respect to that particular reactant. Example ionic exchange reaction which ... WebThe molecularity of the three most common types of elementary steps are as follows: unimolecular-- A --> products and Rate = k [A]; bimolecular -- A + A --> products and Rate = k [A]^2; and bimolecular -- A + B --> products and Rate = k [A] [B].
