Expert Solution
Step 1-introduction

For any chemical reaction rate law is defined as the change in any one of the reactants or products per unit time. Initially, there is no product, only reactant is present. As the reaction proceeds, Concentration of reactant decreases and concentration of product increases. So, the rate of the reaction can be described as :

Rate of the reaction= Decrease in the concentration of reactant/Time taken

Rate of the reaction =- [R]/t

Rate of the reaction in terms of product= [P]/t
