11. Parallel reactions in CSTR The following reactions take place in a CSTR: A > 3/2 B ; A –2 > 1/2 C. The first one follows the rate law ri = kj[A]² (i.e. it is not 1st order!); the second one is simple. a) Analyse the dependence of the composition of the reactor on its space-time 7. b) B is the desired product. What space-time corresponds to desirable conversion of 90%? What is the undesirable conversion under these conditions? c) Plot the dependence of the composition on the space-time of the reactor. Use units min for the space-time axis. d) The undesired product C has a maximum as a function of t. Find its position and magnitude, and mark it on the plot. Parameters: k = 8.1×10-4 M²s1; k2 = 6.6×10ª s1; [A]o = 0.45 M.
