Equilibrium in an Ideal-Gas Mixture

One of the most important aspects of the application of ST is that it provides a method of explicit calculation of the equilibrium constant of a chemical reaction. From 

Because of their central importance to almost all applications of ST to chemistry and biochemistry, we shall now study in detail some aspects of systems in chemical equilibrium.

One of the earliest examples of Gibbs energy minimisation applied to a multi-component system was by White et al. (1958) who considered the chemical equilibrium in an ideal gas mixture of O, H and N with the species H, H2, HjO, N, N2, NH, NO, O, O2 and OH being present. The problem here is to find the most stable mixture of species. The Gibbs energy of the mixture was defined using Eq. (9.1) and defining the chemical potential of species i as...
