Question

write difference between molecularity and order of reaction​

Answer 1

Answer:

Definition

Molecularity: Molecularity is the number of molecules or ions that take part in the rate determining step.

Order of Reaction: Order of reaction is the sum of the powers to which the reactant concentrations are raised in the rate law equation.

The molecularity and order of reaction are two different terms used to explain the rate of a chemical reaction. The molecularity is obtained from the reaction mechanism. The order of reaction is obtained from the rate law of the reaction. The difference between molecularity and order of reaction is that molecularity is a theoretical concept whereas order of reaction is determined experimentally.
