WebMass transfer between two phases 2 • For a two phase system not at equilibrium (concentrations in the two phases are not as predicted by Henry's law), mass transfer will occur to bring it to equilibrium. There must be concentration gradient in the direction of diffusion within each phase. E.g. diffusion of a soluble gas such as ammonia between WebView Diffusion Mass Transfer 2.ppt from CHEMISTRY ANALYTICAL at University of Baghdad.
