P12-16B The elementary reversible liquid-phase reactiontakes place in a CSTR with a heat exchanger. Pure A enters the reactor.(a) Derive an expression (or set of expressions) to calculate G(T) as a function of the heat of reaction, equilibrium constant, temperature, and so on. Show a sample calculation for G(T) at T = 400 K.(b) What are the steady-state temperatures? (Ans.: 310, 377, 418 K.)(c) Which steady states are locally stable?(d) What is the conversion corresponding to the upper steady state?(e) Vary the ambient temperature Ta and make a plot of the reactor temperature as a function of Ta, identifying the ignition and extinction temperatures.(f) If the heat exchanger in the reactor suddenly fails (i. e., UA =
