Chapter 7, Problem 7E.3E

(a)

Interpretation Introduction

Interpretation:

The factor by which rate of the reaction is increased at $\text{298}\text{K}$ has to be determined.

Concept Introduction:

The Arrhenius equation is the relationship between the temperature and rate constants and also involves the activation energy.  The mathematical for of Arrhenius equation involving the two rate constants $k_{\text{r1}}$ and $k_{\text{r2}}$ is shown below.

    $\ln \frac{k_{\text{r2}}}{k_{\text{r1}}}=-\frac{E_{\text{a2}}-E_{\text{a1}}}{RT}$

(b)

Interpretation Introduction

Interpretation:

The factor by which rate of the reaction is increased at $\text{350}\text{K}$ has to be determined.

Concept Introduction:

Same as part (a).
