Vapor liquid equilibrium vle amp phase diagram relative volatility raoult s law and ideal solutions and azeotropic mixtures maximum and minimum boiling vaporliquid equilibrium wikipedia april 17th 2019 in thermodynamics and chemical engineering the vaporliquid equilibrium vle describes the distribution of a chemical. Lcst is the lowest t at which phase separation occurs 3.
Raoults law and ideal mixtures of liquids. For a binary mixture in two phases the degree of freedom f is given by f m π 2 2 2 2 2 41 1 as an example we will use the benzene toluene vapor liquid system. You will remember that because of raoults law if you plot the vapour pressure of an ideal mixture of two liquids against their composition you get a straight line graph like this.

Boiling occurs between 73 c and 82 c at which point all of the liquid has been converted into vapor. Raoults law and ideal mixtures of liquids explains how raoults law applies to cases of two volatile liquids which form an ideal mixture. B normal boiling point for a 90 c. It explains how a phase diagram for such a mixture is built up and how to interpret it.
