Explain vapour liquid equilibrium (VLE).

The vapor–liquid equilibrium (VLE) describes the distribution of a chemical species between the vapor phase and a liquid phase. The concentration of vapor in contact with its liquid, especially at equilibrium, is often expressed in terms of vapor pressure, which will be a partial pressure (a part of the total gas pressure) if any other gas(es) are present with the vapor. The equilibrium vapor pressure of a liquid is in general strongly dependent on temperature. At vapor–liquid equilibrium, a liquid with individual components in certain concentrations will have an equilibrium vapor in which the concentrations or partial pressures of the vapor components have certain values depending on all of the liquid component concentrations and the temperature.

What are the limitations of Raoult's Law.

Raoult’s law is applicable only to very dilute solutions. The second limitation is that it's applicable to solutions containing non-volatile solute only. The third limitation is that it's not applicable to solutes that dissociate or associate in the particular solution.
