WebAug 30, 2024 · This is caused by a principle called vapor pressure. In chemistry, vapor pressure is the pressure that is exerted on the walls of a sealed container when a substance in it evaporates (converts to a gas). [1] To find the vapor pressure at a given temperature, use the Clausius-Clapeyron equation: ln (P1/P2) = (ΔHvap/R) ( (1/T2) - (1/T1)). WebIf a non-volatile solute B (it has zero vapor pressure, so does not evaporate) is dissolved into a solvent A to form an ideal solution, the vapor pressure of the solution will be lower than that of the solvent. In an ideal solution of a nonvolatile solute, the decrease in vapor pressure is directly proportional to the mole fraction of solute:
