Shapiro, N.Z.Shapley, L.S.2005-07-192005-07-191966-07http://udspace.udel.edu/handle/19716/1390This study mathematically investigates equilibrium properties of certain two-phase chemical systems. The different types of equilibrium compositions and the conditions that govern them are determined. Then effects of linear variation in the chemical inputs are studied; e.g., the effects on a multisubstance fluid, separated by a semipermeable membrane, to which another field is slowly added. Among other results, it is shown that the relative sizes of the two phases will always change monotonically, but that the absolute sizes may fluctuate.1894860 bytesapplication/pdfen-USMembrane EquilibriaChemical InputsLinear VariationTechnical Report
