    In your chemistry classes, a teacher might give you an exercise to find the vapor pressure or enthalpy of vaporization. Let's solve one to help you fully understand the Clausius-Clapeyron equation. Water has an enthalpy of vaporization of 40660 J / mol (ΔH vap). Its vapor pressure is 102325 Pa (P 1) at a temperature of 280 K (T 1).

    30 sty 2023 · The partial vapor pressure of a component in a mixture is equal to the vapor pressure of the pure component at that temperature multiplied by its mole fraction in the mixture. Raoult's Law only works for ideal mixtures. In equation form, for a mixture of liquids A and B, this reads: PA = χAPo A (1) (1) P A = χ A P A o.
