The liquid-phase reaction in Problem P11-3B is to be carried out in a semi-batch reactor. There are 500 mol of A initially in the reactor at 25°C. Species B is fed to the reactor at 50°C and a rate of 10 mol/min. The feed to the reactor is stopped after 500 mol of B has been fed.

(a) Plot and analyze the temperature Qr, Qg and conversion as a function of time when the reaction is carried out adiabatically. Calculate to t = 2 h.

(b) Plot and analyze the conversion as a function of time when a heat exchanger (UA = 100 cal/min · K) is placed in the reactor and the ambient temperature is constant at 50°C. Calculate to t = 3 h.

(c) Repeat part (b) for the case where the reverse reaction cannot be neglected.

New parameter values:

For the reverse reaction: kr = 0.1 min 1 at 300 K with Er = 16 kcal/mol
