WebThe partial vapour pressure of a component in a mixture is equal to the vapour 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: In this equation, PA and PB are the partial vapour pressures ...
