What are the Limitations of Fick's First Law in Catalysis?
While Fick's First Law provides a good approximation for diffusion, it has limitations:
It assumes a steady-state process, which may not be valid for all catalytic reactions. It does not account for convective transport that could occur alongside diffusion. It assumes a linear concentration gradient, which may not always be the case in complex pore structures.
Despite these limitations, Fick's First Law remains a cornerstone in the study of diffusion in catalytic systems.
