Why I prefer the Maxwel-Stefan diffusion formulation

The accurate description of molecular diffusion is important in the design and development of several processes of interest to physicists, chemist, and engineers. It is common practice to use the Fick’s law to describe molecular diffusion. Here, the diffusion flux is linearly related to the concentration gradient, that is considered as the driving force for diffusion. We argue that the proper driving force for diffusion is the gradient of the chemical potential. The diffusion fluxes may be linearly related to the gradients of the chemical potential gradients using either the Onsager, or Maxwell-Stefan formulations. My preference is for the M-S formulation, for the reasons outlined in this talk. R. Krishna, Diffusing Uphill with James Clerk Maxwell and Josef Stefan, Chem. Eng.
