Chapter 13, Problem 13.38QP

Interpretation Introduction

Interpretation: Raoult’s law, each of the term in Raoult’s law with units has to be briefly described. The term ideal solution has to be explained.

Concept introduction:

Raoult’s law: Raoult’s law states that partial pressure of the substance above a solution is equal to its pure vapor pressure and mole fraction of the substance.

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

Ideal solution is a solution which obeys Raoult’s law

Partial pressure of a gas in a mixture of gases is the pressure of that gas when it alone. Units of partial pressure can be $\text{atm,}\text{mmHg,}\text{Pa}\text{or}\text{Torr}\mathrm{...}$

A mole fraction of a molecule in a mixture is the ratio of number of moles of particular molecule to the sum of number of moles of all molecules in the mixture. Mole fraction does not have any units.
