Gibbs-duhem-margules laws

  • N. A. Gokcen
Section I: Basic and Applied Research


The Margules equation, which is in accord with the GibbsDuhem relation, is an important basic equation of thermodynamics. It yields an elegant formulation of the laws of Raoult and Henry. Its relationships with theoretical equations are briefly discussed. The Margules equation should also be applicable to the ionic solutions if it can represent any other equation capable of representing the excess partial Gibbs energy of a solution.
