Chapter 9, Problem 28QRT

Interpretation Introduction

Interpretation:

The vapour pressure of the liquid at ${130}^{\circ }C$ has to be determined.

Concept Introduction:

Clausius-Clapeyron equation:

  $\ln \left(\frac{P_2}{P_1}\right)=-\frac{{\Delta }_{Vap}H}{R}\left[\frac{1}{T_2}-\frac{1}{T_1}\right]$

Where,

${\Delta }_{Vap}H=$ Enthalpy of vaporization

$P_1$ and $P_2$ are two sets of pressures and $T_1$ and $T_2$ are two sets of absolute temperatures.

$R$ is universal gas constant.
