Introduction
More than one phases coexist at the same temperature and pressure.
K-Values
K-values is a phase-equilibrium ratio, for vapor-liquid systems,
is the mole fraction of a species in vapor phase, and
is the mole fraction of a species in liquid phase.
For ideal solutions,
K-values can be used for calculating bubble and dew points.
