1. Note that if the internal diffusion resistance of the catalyst pellet was small (i.e. that the
diffusion in the pellet was fast enough to be uniform throughout at the concentration outside of the
4
na’kC, . The ratio of the rate from 2
3
pellet) then the reaction rate would be given by Rate =
to this rate is called an effectiveness factor. Determine the effectiveness factor for the spherical
pellet.
