Chapter 16, Problem 85E

Interpretation Introduction

Interpretation : Linear negative slope of the plot of ln(P_vap) versus 1/T(K)should be explained.

Concept Introduction :

The Clausius-Clapeyron equation is represented as follows:

  $\ln \left(\frac{P_{vap1}}{P_{vap2}}\right)=\frac{\Delta H_{vap}}{R}\left(\frac{1}{T_2}-\frac{1}{T_1}\right)$

Here,

  $P_{vap1}\text{ and }{P}_{vap2}\text{ = vapor pressures}$

  $T_1{\text{ and T}}_2=\text{ temperatures }$

  $\Delta H_{vap}=\text{ Enthalpy of vaporization}$

  $R=\text{ Universal gas constant}$
