Chapter 11, Problem 68E

(a)

Interpretation Introduction

Interpretation:

The highest vapour pressure of given solvent and mixture should be explained.

Concept Introduction:

Raoult's law states that the fractional vapor pressure of each constituent of a perfect mixture of liquids is equivalent to the vapor pressure of the clean constituent multiplied by its mole fraction in the mixture.

${\text{P}}_{\text{soln}}{\text{=χ}}_{\text{solvent}}{\text{P}}^{\text{ο}}{}_{\text{solvent}}$

${\text{χ}}_{\text{solvent}}\text{=mole}\text{fraction}$

${\text{P}}^{\text{ο}}{}_{\text{solvent}}\text{=vapour}\text{pressure}\text{of}\text{solvent}$

${\text{P}}_{\text{soln}}\text{=solution}\text{vapour}$
