You are designing a reactor system for carrying out the constant-density liquid-phase reaction

which has the rate law

(a) What system (i.e., type and arrangement) of flow reactors, either one alone or two in series, would you recommend for continuous processing of a feed of pure A in order to minimize the total reactor volume? (90% conversion of A is desired.)
(b) What reactor size(s) should be used?
(c) Plot the conversions and concentrations of A and B as a function of plug-flow reactor volume.


Additional information:

k1 = 10.0 (lb-mol/ft 3) 0.5 h -1
k 2 = 6.0 ft 3/lb mol
feed = 100 lb mol/h of pure A
C AO = 0.25 lb mol/ft 3
total pressure = 2000 kPa
