Chapter 4, Problem 4B.3P

Interpretation Introduction

Interpretation: The vapour pressure of hair spray using Freon-$12$ at $40{}^{°}\text{C}$ has to be estimated.

Concept introduction: Clausius-Clapeyron expression correlates the pressure and temperature for the processes that includes the phase transitions.  Clausius-Clapeyron equation is shown below.

    $\ln \left(\frac{p_2}{p_1}\right)=-\frac{\Delta H_{\text{vaporization}}}{R}\left(\frac{1}{T_2}-\frac{1}{T_1}\right)$
