Chemical Reaction Engineering If the catalyst pore size is small in comparison with the mean free path, collisions with the pore wall controls the process'. The diffusivity under this condition is called 'Knudsen diffusivity', which is affected by the Temperature Neither A nor B Both A & B Pressure Temperature Neither A nor B Both A & B Pressure ANSWER DOWNLOAD EXAMIANS APP
