Chapter 7, Problem 7B.9E

(a)

Interpretation Introduction

Interpretation:

The rate constant of the reaction has to be determined.

Concept Introduction:

According to the integrated rate law for the first order reaction, the concentration of reactant is the exponential function of time.  The equation that represents the integrated rate law for the first order kinetics is shown below.

    ${\left[\text{A}\right]}_{\text{t}}={\left[\text{A}\right]}_0{\text{e}}^{-k_{\text{r}}t}$

(b)

Interpretation Introduction

Interpretation:

The time required to increase the concentration of $\text{B}$ to $0.030\text{mol}\cdot {\text{L}}^{-1}$ has to be determined.

Concept Introduction:

Same as part (a).
