Question

Can you recall ?
What is meant by order and
molecularity of a reaction ?​

Answer 1

Answer:

The order of reaction is an empirical quantity determined by experiment from the rate law of the reaction. It is the sum of the exponents in the rate law equation. Molecularity, on the other hand, is deduced from the mechanism of an elementary reaction, and is used only in context of an elementary reaction.

Answer 2

Answer:

Molecularity of the reaction can be defined as the total number of reacting species in a rate-determining step. On the other hand, the order of reaction is the summation of powers of concentration of the reactant molecules in the rate equation of the reaction.
