Question

Chemical Engineering: Pore Diffusion. Please answer all parts of the question and provide full, detailed solution.

A gas-phase reaction is being conducted on the internal surface of POROUS spherical catalyst pellets of radius R. Plot the concentration profile C_A(V) inside the pellet as a function of distance r for the following three values of the Thiele modulus phi phi = 0.1; phi = 1; phi = 10. Which of the above values of phi would be preferred for an industrial packed bed reactor? Give clear reasons. What is the corresponding value of the effectiveness factor eta?
