Chapter 8, Problem 8.43E

Interpretation Introduction

Interpretation:

The value of the temperature coefficient for given reaction is to be stated. Whether higher temperatures favor isotopically mixed $\text{HD}$ or the isotopically pure ${\text{H}}_{\text{2}}$ and ${\text{D}}_{\text{2}}$ is to be stated.

Concept introduction:

The relation of temperature coefficient with $\Delta H°$ is given below.

$\Delta H°=-nf\left(E°-T\frac{\partial E}{\partial T}\right)$

The value $\frac{\partial E}{\partial T}$ is the temperature coefficient. It also has a value as written below.

${\left(\frac{\partial E}{\partial T}\right)}_p=\frac{\Delta S°}{nF}$
