WebMay 24, 2024 · A deviation from Raoult's law can only be measured experimentally. However, for some solutions, you can predict whether the deviation will be positive or … WebRaoult’s law states that the vapour pressure of a solvent above a solution is equal to the pure solvent’s vapour pressure at the same temperature scaled by the solvent mole fraction in the solution. Meanwhile, according to Dalton’s law, the overall pressure of a mixture of non-reacting gases equals the sum of their individual pressures.
