Chapter 5, Problem 5.23E

Interpretation Introduction

Interpretation:

When $\Delta H_{Vap}$ is small or large, the vapor pressure of the liquid is more sensitive to changes in temperature has to be identified.

Concept introduction:

The relationship to plot is In P versus 1/T is given below,

    $\text{In P}=\frac{-\Delta H_{vap}^o}{\text{RT}}+\frac{\Delta S_{vap}^o}{\text{ R}}$

  $\begin{array}{l}\text{Slope}=\frac{-\Delta H_{vap}^o}{\text{R}},\\ \\ Intercept=\frac{\Delta S_{vap}^o}{\text{R}}\end{array}$
