Order and molecularity

WebApr 30, 2024 · The molecularity of a reaction is the number of molecules reacting in an elementary step. Reactions can be unimolecular (one reacting molecule), bimolecular (two reacting molecules) or termolecular (three reacting molecules).

WebJul 19, 2024 · The order should not be confused with molecularity which describes the number of species reacting in a postulated elementary reaction and which is always a small positive number. Effectively this means 1 or 2. A molecularity of 3 is not impossible but the chance of three reactive species colliding at the same time is vanishingly small. WebOct 4, 2024 · Many reactions have the order of reaction different from the molecularity of the reaction. This case is mainly when one reactant is present in significant excess. Examples are Hydrolysis of ethyl acetate and inversion of cane sugar in an aqueous solution. Above reaction, the molecularity of each reaction is two, and the order of a reaction is one.
