Chapter 4, Problem 4B.6E

Interpretation Introduction

Interpretation:

The values of A and B in order to calculate the vapour pressure in torr have to be determined.

Concept Introduction:

The Clausius-Claypeyron equation:

The Clausius-Claypeyron equation can be written as

  $\begin{array}{l}\ln \left(p/kPa\right)=\ln \left(p^{\prime }/kPa\right)+\frac{{\Delta }_{vap}H}{R{T}^{\prime }}-\frac{{\Delta }_{vap}H}{RT}\\ \\ \ln \left(p/kPa\right)=A-\frac{B}{T}\\ \\ Where,\\ \\ A=\ln \left(p^{\prime }/kPa\right)+\frac{{\Delta }_{vap}H}{R{T}^{\prime }}\\ \\ B=\frac{{\Delta }_{vap}H}{RT}\\ \\ {\Delta }_{vap}H=Enthalpyofvapourisation\\ \\ R=Universalgascons\tan t\\ \\ kPa=KiloPascal\\ \\ p=vapourpressure\\ \\ T=Transitiontemperature\end{array}$
