Chapter 11, Problem 47QRT

(a)

Interpretation Introduction

Interpretation:

Arrhenius equation for each temperature has to be written.

Concept Introduction:

The temperature dependence of rate constant can be explained through Arrhenius equation.

  $k=A{e}^{\frac{-E_a}{RT}}$

Where $k$ is the rate constant, $A$ is the frequency factor, $E_a$ is the activation energy, $R$ is the universal gas constant and $T$ is the temperature.

(b)

Interpretation Introduction

Interpretation:

An expression for the ratio of two rate constants $\frac{k_1}{k_2}$ has to be derived by combining two equations of part (a).

Concept Introduction:

Refer to part (a).
