Chapter 16, Problem 16.77P

Interpretation Introduction

Interpretation:

The vapor pressures of carbon tetrachloride and ethyl acetate in a solution at ${50}^{\circ }C$ containing $25g$ of carbon tetrachloride dissolved in $100.0g$ of ethyl acetate have to be calculated.

Concept Introduction:

Raoult’s law:

It states that the equilibrium vapor pressure of the solvent over a solution is directly proportional to the mole fraction of the solvent in the solution.

The vapor pressure of each component is given below.

  $P=\chi P^{\circ }$

Where, $P$ is vapour pressure of one component, $\chi$ is the mole fraction of solute and $P^{\circ }$ is vapour pressure of the pure solvent.
