The elementary reversible liquid-phase reaction (A + B) takes 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 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? (c) Vary the ambient temperature T, and make a plot of the reactor temperature as a function of T., identifying the ignition and extinction temperatures. (d) If the heat exchanger in the reactor suddenly fails (Le., UA = 0), what would be the conversion and the reactor temperature when the new upper steady state is reached? = = Additional information: UA = 3600 cal/min. K Cp = Cha = 40 cal/molK PB AHRx = -80,000 cal/mol A Koq = 100 at 400 K k = 1 min at 400 K Ambient temperature, T, = 37C EIR = 20,000 K V = 10 dm 1 dm3/min FAO 10 mol/min = Va = E = Feed temperature.
