In this lecture we will be discussion the vapor pressure of solutions and Raoult's Law.

Raoult’s law: Vapor pressure of solution is equal to the vapor pressure of the pure solvent multiplied by the mole fraction of the solvent in the solution.

Psolution = Xsolvent • P°solvent

This should a relatively familiar concept. In chapter 10, we discussed how the vapor pressure of a liquid decreased when a solute was added to it.
