Qusetion: The system in Figure Q5.15 has two stirred tanks; the first is a heat ex changer, and the second is a CSTR. The product of the reactor exchanges
heat with the feed in the heat exchanger. A single, zeroth-order reaction of A → products occurs in the second reactor with a heat of reaction (-?Hnn).
(a) Formulate a model of the system to predict the temperature response in both tanks to a change in the feed temperature with all flows constant, and linearize the model. Determine to which process structure category this process belongs.
(b) Determine under what conditions the system would experience (i) periodic behavior and (ii) unstable behavior,
(c) Discuss your results and limitations in the model.
