The isothermal, gas phase, first order reaction of A occurs within the pores of a spherical catalyst pellet. The reactant concentration halfway between the external surface and the center of the pellet is equal to one-fourth the concentration at the external surface.

(1). What is the relative concentration of A near the center of the pellet?

(2) By what fraction should the pellet diameter be reduced to give an effectiveness factor of 0.55?

The gas phase reaction AàB occurs on the surface of a catalyst in the form of a wire gauge. The bulk concentration of the species A is 0.002 kmol/m3 and the rate of reaction of A is measured at 0.08 kmol per hour per m2 area of the catalyst. If the reaction is instantaneous and the entire diffusional resistance to the transport of the reactive species from the bulk gas to the catalyst surface is offered by a stagnant film...

Problem 4. The first order reaction A →B was carried out over two different-sized spherical pellets. The pellets were contained in a spinning basket reactor that was operated at sufficiently high rotation speeds that external mass transfer resistance was negligible. The results of two experimental runs made under identical conditions are given in Table 1. Table 1.
