Chapter 7, Problem 7.15E

Interpretation Introduction

Interpretation:

The total equilibrium pressure of the vapor in equilibrium with a $2:1$ molar ratio of hexane $\left({\text{C}}_{\text{6}}{\text{H}}_{\text{14}}\right)$ and cyclohexane $\left({\text{C}}_{\text{6}}{\text{H}}_{\text{12}}\right)$ is to be calculated. Also, the answer is compared to the answer from the previous exercise.

Concept introduction:

According to Raoult’s law, the solution that consists of volatile liquids has partial pressure of each component directly proportional to the mole fraction of that component.
