Problem #2. Consider a porous catalyst pellet with a diameter of 6 mm. The porosity of the pellet is 0.55, the tortuosity factor is 4.0, the internal surface area is 200 m /g, and the pellet density is 2.0 g/cm . The following first- order reaction occurs in the pellet at a temperature of 475 K: A - B where (-rA) = kCA The rate constant at the reaction temperature has a value of 0.1 s. The molecular weight of A and B is 16 g/mol. The bulk diffusion coefficient of A in the reacting mixture is 5 x 10-5 m /s. Determine the value of the effectiveness factor in the pellet
