Gibbs theorem

WebThe proof of Gibbs' theorem, which was given by J. W. Gibbs, is published in his paper «On the Equilibrium of Heterogeneous Substances» [1, с. 55-353]. It consists in deriving a formula expressing the Gibbs theorem from other formulas. Dalton's law according to which the pressure of a mixture of ideal gases is equal to the Gibbs himself did not see it as paradoxical. Distinguishability of two materials is a constitutive, not a thermodynamic, difference, for the laws of thermodynamics are the same for every material, while their constitutive characteristics are diverse. See more In thermodynamics, the entropy of mixing is the increase in the total entropy when several initially separate systems of different composition, each in a thermodynamic state of internal equilibrium, are … See more In ideal species, intermolecular forces are the same between every pair of molecular kinds, so that a molecule "feels" no difference between itself and its molecular neighbors. This is the reference case for examining corresponding mixing of non-ideal species. See more Mixing with and without change of available volume In the established customary usage, expressed in the lead section of this article, the entropy of mixing comes from two mechanisms, the intermingling and possible … See more • CALPHAD • Enthalpy of mixing • Gibbs energy See more Ideal and regular solutions The above equation for the entropy of mixing of ideal gases is valid also for certain liquid (or … See more Since thermodynamic entropy can be related to statistical mechanics or to information theory, it is possible to calculate the entropy of mixing using these two approaches. … See more For entropy of mixing to exist, the putatively mixing molecular species must be chemically or physically detectably distinct.
