P8-9. Exam Problem. The elementary liquid-phase series reaction Ak1B is carried out in a 500dm3 batch reactor. The initial concentration of A is 1.6 mol/dm 3 . The desired product is 8 , and separation of the undesired product C is very difficult and costly. Because the reaction is carried out at a relatively high temperature, the reaction is easily quenched. (a) Plot and analyze the concentrations of A, , and C as a function of time. Assume that each reactionis irreversible, with k, 0.4 h-1 and k3=0.01h1 (b) Plot and analyze the concentrations of A,B, and C as a function of time when the firat reaction is reversible, with k, =0.3 h-1. (c) Plot and analyce the concentrations of A,B, and C as a function of time for the case where both reactions are reversible, with k, " 0.005h1 (d) Compare (a), (b), and (c) and describe what you find. (e) Vary k1,k1k2, and k2, Explain the consequence of k1>100 and k2
