Chapter 13, Problem 60QRT

Interpretation Introduction

Interpretation:

The graph that correctly represents Raoult’s law has to be explained.

Concept Introduction:

Raoult’s law: Raoult’s law states that solvent partial pressure over a solution is equal to vapor pressure of pure solvent multiplied with mole fraction of the solvent.

  ${\text{P}}_{\text{1}}{\text{= χ}}_{\text{1}}{\text{P}}^{\text{°}}{}_{\text{1}}$.

Where,

${\text{P}}_{\text{1}}$ is Partial pressure of solvent

${\text{P}}_{\text{1}}^{\circ }$ is Partial pressure of its pure solvent.

${\text{χ}}_{\text{1}}$ is Mole fraction of the solvent.

The solution that obeys Raoult’s law is defined as ideal solution.
