Question

Define the term order and molecularity of a reaction

Answer 1

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.

Answer 2

Hey !!

Order of a reaction: The order of reaction is defined as the sum of powers of concentration terms of reactants in rate equation of a reaction

Molecularity: The number of atoms or ions or molecules participating in rate determining step is called molecularity of a reaction
