Chapter 20, Problem 20.39E

Interpretation Introduction

Interpretation:

Whether the plot of the base-10 logarithm of the concentration, $\log {\left[\text{A}\right]}_t$, versus time give a straight-line plot for a first order reaction is to be stated. The slope of this line is to be predicted.

Concept introduction:

The expression for the first order reaction is given by,

${\left[\text{A}\right]}_t={\left[\text{A}\right]}_0\exp \left(-kt\right)$

Where,

• $k$ is the rate constant.

• ${\left[\text{A}\right]}_t$ is the concentration of A at time $t$.

• ${\left[\text{A}\right]}_0$ is the concentration of A at $t=0$.
