(a)

Interpretation Introduction

Interpretation:

Which of the given options will change the value of rate constant of a given reaction has to be explained.

Concept introduction:

Order of a reaction: The sum of exponents of the concentrations in the rate law for the reaction is said to be order of a reaction.

Rate law: It is an equation that related to the rate of reaction to the concentrations or pressures of substrates (reactants).  It is also said to be as rate equation.

• Depends on order of the chemical reaction, the rate law or rate equation also varies.
