Raoult's Law describes how the vapor pressure of an ideal solution is dependent on the vapor pressures of each chemical component and their respective mole fractions in the solution. It is particularly useful for predicting the behavior of solutions where the solute-solvent interactions are similar to the solvent-solvent interactions, making it applicable primarily to ideal solutions.

Raoult's Law

Vapor pressure is the pressure exerted by the vapor of a liquid or solid in equilibrium with its condensed phases at a given temperature, reflecting the tendency of particles to escape into the gaseous phase. It is a critical factor in determining boiling points, evaporation rates, and phase transitions in various substances.

vapor pressure

An ideal solution is a homogeneous mixture of substances that obeys Raoult's Law, where the interactions between unlike molecules are similar to those between like molecules. This results in a linear relationship between the partial vapor pressure of each component and its mole fraction in the solution, leading to no enthalpy change upon mixing.
