Introduction[edit]

More than one phases coexist at the same temperature and pressure.

K-Values[edit]

K-values is a phase-equilibrium ratio, for vapor-liquid systems,

K_i = y_i/x_i

y_i is the mole fraction of a species in vapor phase, and x_i is the mole fraction of a species in liquid phase.

For ideal solutions,

K_i = P_i^S/P

K-values can be used for calculating bubble and dew points.
