The following reaction is a single-step, bimolecular reaction:

Concepts and reason
A chemical reaction in which two molecules undergo Collison and colloid with each other is called as bimolecular reaction.
Rate of the reaction is the change in the concentrations of the reactants or products per unit time.
Calculate the rate by substituting the concentration values of the reactants in the expression of the rate of the reaction.
