The complex gas-phase reactions are elementary

and carried out in a PFR with a heat exchanger. Pure A enters at a rate of 5 mol/min, a concentration of 0.2 mol/dm³, and temperature 300 K. The entering temperature of an available coolant is 320 K.
Additional information:

(a) Plot (F_A, F_B, F_C) on one graph and (T and T_a) on another along the length of the reactor for adiabatic operation, heat exchange with constant T_a, and co-current and  countercurrent heat exchange with variable T_a. Only turn in a copy of your code and output for co-current exchange.  Adiabatic operation
(b) What is the maximum temperature and at what reactor volume is it reached?
(c) At what reactor volume is the flow rate of B a maximum, and what is F_Bmax at this value? Constant T_a 
(d) What is the maximum temperature and at what reactor volume is it reached?
(e) At which reactor volume is the flow rate of B a maximum, and what is FBmax at this volume? Co-current exchange
(f) At what reactor volume does Ta become greater than T? Why does it become greater? Countercurrent exchange
(g) At what reactor volume does Ta become greater than T?
