Chapter 11, Problem 11.115CHP

Interpretation Introduction

Interpretation:

The vapour pressure of the given prepared solution of bromine in tetrachloromethane at $300\text{ K}$ has to be calculated.

Concept introduction:

Raoult’s law:

Raoult’s law for ideal solution states that the mole fraction of the solvent is directly proportional to the vapor pressure of an ideal solution. Raoult’s law can be expressed by the equation,

${\text{P}}_{\text{solution}}{\text{=χ}}_{\text{solvent}}{\text{P°}}_{\text{solvent}}$

Where,

${\text{P}}_{\text{solution}}$  = observed vapor pressure of the solution

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

${\text{P°}}_{\text{solvent}}$ = vapor pressure of pure solvent
