For the optimum temperature progression in a plug flow reactor in Example 9.4 (C_A0 = 4 mol/liter, F_A0 = 1000 mol A/min, X_A0 = 0.8, T = 5°C, T_max = 95°C) and feed and product both at 25°C, how much heating and cooling would be needed.

(a) For the feed stream?

(b) In the reactor itself?

(c) For the stream leaving the reactor?
