What is the Role of Diffusion in Managing Concentration Gradients?
Diffusion is the primary mechanism that helps in mitigating concentration gradients. There are two types of diffusion relevant in catalysis: molecular diffusion and Knudsen diffusion. Molecular diffusion dominates when the pore size of the catalyst is relatively large, while Knudsen diffusion becomes significant in very small pores. The efficiency of these diffusion processes determines how effectively concentration gradients can be managed.
