Internal Transport: Mass Balance and Maxwell-Stefan Equation

This lecture covers the internal transport phenomena related to mass balance in single pores, Knudsen diffusion, and the application of the Maxwell-Stefan Equation. It discusses the independence of diffusivity on pore size, molecular weight, and other molecules. The lecture emphasizes the occurrence of diffusion in both bulk and Knudsen regimes, with a focus on equimolar counter-diffusion and high dilution scenarios.
