Local composition for a binary mixture of particles on a three-dimensional ising lattice / Simonin, Jean-Pierre in Industrial & engineering chemistry research, Vol. 51 N° 47 (Novembre 2012)

The local composition is studied as a function of composition and of the value of the interchange energy (δ = 2EAB ― EAA ― EBB). The MC results are used to assess the accuracy of analytical theories proposed in the literature as a function of the interchange energy. The local composition is shown to obey an exact limiting law at high dilution of one component, thus providing a simple expression for the limiting activity coefficient. The activity coefficients of the species and the entropy per particle are computed from the MC data.
