Chapter 11, Problem 4ALQ

Interpretation Introduction

Interpretation:

The ${\text{ΔH}}_{\text{Solution}}$ relate to deviations from Raoult's law should be calculated.

Concept introduction:

• Raoult's law:

  The mole fraction of a solute is related to the vapor pressure of the solution thus,

$\begin{array}{l}{\text{P}}_{\text{solution}}{\text{=P°}}_{\text{solvent}}{\text{X}}_{\text{solvent}}\mathrm{......}\text{(1)}\\ \\ \text{P}\text{is}\text{vapor pressure}\text{of the solution}\\ \\ {\text{P°}}_{\text{solvent}}\text{pressure}\text{of the solvent}\\ \\ {\text{X}}_{\text{solvent}}\text{ mole fraction of}\text{solvent}\end{array}$
