3. 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 pellet) then the reaction rate would be given by Rate =-- ra kC, . The ratio of the rate from 2 3 to this rate is called an effectiveness factor. Determine the effectiveness factor for the spherical pellet.

3. 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 pellet) then the reaction rate would be given by Rate =-- na kC, . The ratio of the rate from 2 3 to this rate is called an effectiveness factor. Determine the effectiveness factor for the spherical pellet.
