Expert Solution
Step 1: Molecularity

Molecularity is defined as the number of reactant molecules colliding in a single step to form products. For elementary reactions, molecularity can be easily defined by adding the number of reactants taking part in the reaction. However, for complex reactions, the molecularity cannot be defined easily as there are a number of steps involved to form products.
