Chapter 8, Problem 8.10YT

(a)

Interpretation Introduction

Interpretation:

The percentage of molecules having enough energy to surmount an energy barrier of $\text{20 kJ/mol}$ at $\text{0 °C}$ is to be estimated using figure $\text{8-5}$.

Concept introduction:

The percentage of molecules with sufficient energy decreases as the size of the energy barrier increases. As the temperature increases, the percentage also increases.

(b)

Interpretation Introduction

Interpretation:

The percentage of molecules having enough energy to surmount an energy barrier of $\text{20 kJ/mol}$ at $\text{100 °C}$ is to be estimated using figure $\text{8-5}$.

Concept introduction:

The percentage of molecules with sufficient energy decreases as the size of the energy barrier increases. As the temperature increases, the percentage also increases.
