Structural Biochemistry/Phase Equilibria

IntroductionEdit

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

K-ValuesEdit

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.
