The vapor liquid equilibrium relation for an ideal binary system is given by

y^*_A = (Î±_ABx_A)/[1 + (Î±_AB - 1)x_A]

Here x_A and y^*_A are the mole fractions of species A in the liquid and vapor, respectively. The relative volatility (Î±_AB) is greater than unity.

The liquid mole fraction x_A at which the maximum difference between the equilibrium vapor mole fraction and liquid mole fraction occurs is
