Expert Solution

Step 1: Introduction to molecularity :

Molecularity :

Molecularity of reaction is defined as number of molecules which collide together to produce the product. The molecularity concept is valid for elementary reaction (a chemical reaction wherein one or more reactants collide directly to form a product in a single step ).For Elementary reaction molecularity is simply the sum of stoichiometric coefficients of reactants taking part in reaction
