What is Equilibirum Vaporization Ratio ?

The Equilibrium vaporization ratio or K value is defined as the ratio of mole fraction of the component in the vapor phase to the mole fraction of the same component in the liquid phase. Generally, the K-value is a function of temperature, pressure and composition (xi and yi). It is even defined as the ratio of fugacity coefficient in the liquid phase to vapor phase. For Ideal Liquid mixtures and Ideal gas, the k-value is the ratio of equilibrium vapor pressure to total pressure, i.e. the k-value is independent of composition. For dilute mixtures, even non-ideal, the k-value is a function of henry's constant.
