2. a simple liquid-phase reaction of a  b follows mass action kinetics and has a rate constant of k = 1 /min. this reaction is carried out in a flow reactor with a volume of 4 l and a molar flow rate of na,0 = 1 mol / min (ca,0 = 1 m). (a) determine the conversion achieved in a single cstr (v = 4 l) (b) determine the conversion achieved in two cstrs (v1 = 2 l and v2 = 2 l). (c) determine the conversion achieved in five cstrs (v1 = v2 = vn = 0.8 l). (d) determine the conversion achieved in ten cstrs (v1 = v2 = vn = 0.4 l). (e) determine the conversion achieved in twenty cstrs (v1 = v2 = vn = 0.2 l). (f) plot the conversion as a function of volume for a pfr.
