Study Notes

Raoult's Law

Raoult's law primarily applies to calculating the vapor pressure of a solution.
Temperature does not impact the applicability of Raoult's law.
Raoult's law holds true for ideal solutions where the solvent-solvent and solute-solute interactions are similar to the solvent-solute interactions.
According to Raoult's Law, the vapor pressure of the solvent decreases when a non-volatile solute is added.
Raoult's law states that the partial vapor pressure of a solvent in a solution is directly proportional to the mole fraction of the solvent in the solution.
