Chapter 19, Problem 19.37QP

(i)

Interpretation Introduction

Interpretation:

The order of the reaction from the given graphs has to be determined.

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.

• We can easily determine the order of reaction from the graph representation of a specific reaction.
• If the given reaction is zero order, we can get plot as straight line by when we plot the concentration of $\left[\text{A}\right]$ versus time.
• If the given reaction is first order, we can get plot as straight line when we plot the natural log of reactant concentration of $\left[\text{A}\right]$ versus time.
• If the given reaction is second order, we can get plot as straight line when we plot the reciprocal of reactant concentration of $\left[\text{A}\right]$ versus time.
