Raoult’s law

Physics

The partial vapour pressure of a solvent is proportional to its mole fraction. If p is the vapour pressure of the solvent (with a substance dissolved in it) and X the mole fraction of solvent (number of moles of solvent divided by total number of moles) then p=p₀X, where p₀ is the vapour pressure of the pure solvent. A solution that obeys Raoult’s law is said to be an ideal solution. In general the law holds only for dilute solutions, although some mixtures of liquids obey it over a whole range of concentrations. Such solutions are perfect solutions and occur when the intermolecular forces between molecules of the pure substances are similar to the forces between molecules of one and molecules of the other. Deviations in Raoult’s law for mixtures of liquids cause the formation of azeotropes. The law was discovered by the French chemist François Raoult (1830–1901) in 1887.

Chemical Engineering

A law that states that the partial pressure exerted by each component in an ideal liquid mixture is the product of the vapour pressure of each component and its mole fraction at the temperature of the liquid expressed as:
$P_{A} = x_{A} p_{A}$

where P_A is the partial pressure, x_A is the mole fraction of component A, and p_A is the vapour pressure. Formulated by French chemist François-Marie Raoult (1830–1901) in 1882.

Geography

This states that the presence of a solute will lower saturation vapour pressure.
