The reactant A decomposes to form an intermediate B, which further decomposes to form a final product C in the following reaction process: A --> 2B k1 = 0.00025 kl/kg cat/s k2 = 0.00015 kl/kg cat/s B --> 3C For a volumetric flow rate of 0.0005kL/s and entering concentration of "A" at 0.5M (ie Cao), calculate the mass of catalyst required in a Packed Bed Reactor (PBR) for the maximum concentration of "B". Note the difference in stoichiometry when calculating relative and net rates. Assume elementary rate laws for both reactions.
