Duhem's theorem

Pierre Duhem (Stanford Encyclopedia of Philosophy)

WebIn theorem 1 we consider the case where G1 is a torsion group, and G 2 is torsion free. However, we consider there the more general situation, v(G1)=n, v(G2)=m, n, m arbitrary positive integers. WebGibbs-Duhem Equation The Gibbs free energy can be defined in two different ways once by subtracting off combinations of entropy S, enthalpy H and temperature T and other as a sum of chemical potentials and amounts of species. The fact that they are equal gives a new relation known as “Gibbs-Duhem Relation.”
