P8-18 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 func- tion 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? (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 7, and make a plot of the reactor temperature as a function of T, identifying the ignition and extinction temperatures. values would you sugges Additional information: UA = 3600 cal/min K = Cp = 40 cal/mol K C = CPB PA AHRX =-80,000 cal/mol A Keq = 100 at 400 K k = 1 min-1 at 400 K Ambient temperature, T = 37°C E/R = 20,000 K V = 10 dm³ Vo = 1 dm³/min FAO = 10 mol/min Feed temperature, T₁ = 37°C
