Chapter 12, Problem 48E

(a)

Interpretation Introduction

Interpretation: The graph of exercise $\text{45}$ is to be considered to answer the question. The concentration of $\text{A}$ is to be calculated for the given time. The first three half-lives is to be calculated for this experiment.

Concept introduction: The change observed in the concentration of a reactant or a product per unit time is known as the rate of the particular reaction. The differential rate law provides the rate of a reaction at specific reaction concentrations.

To determine: The concentration of $\text{A}$ after $\text{9}\text{s}$.
