WebApr 8, 2024 · Deviations from Raoult’s Law can be done if there are adhesive or cohesive forces between two liquids. Negative Deviation When the vapour pressure is lower than expected from the law, this results in a negative deviation. It occurs when forces between particles are stronger than those between particles in pure liquids. WebNon-ideal solutions by definition cannot be dealt with through Raoult's Law. Raoult's Law is strictly for ideal solutions only. A solution shows positive deviation from ideal behaviour when the interaction between them, unlike molecules, is weaker than the like molecules i.e interaction between A-B molecules is weaker than A-A and B-B molecules.

Proposed by French chemist François-Marie Raoult in 1887, it states that the partial pressure of each component of an ideal mixture of liquids is equal to the vapor pressure of the pure component (liquid or solid) multiplied by its mole fraction in the mixture. In consequence, the relative lowering of vapor pressure of a dilute solution of nonvolatile solute is equal to the mole fraction of solute i… flags ccrWebdiagram for transition from Henry’s law regime to Raoult’s law regime.
