The liquid phase reaction: A+B→C Follows an elementary rate law and is carried out isothermally in a flow system. The concentration of A and B feed streams are 2 M before mixing. The volumetric flow rate of each system is 5 dm^3/min, and the entering temperature is 27 C. The streams are mixed immediately before entering. Two reactors are available.

Question
The liquid phase reaction:
A+B→C
Follows an elementary rate law and is carried out isothermally in a flow system. The concentration of A and B feed streams are 2 M before mixing. The volumetric flow rate of each system is 5 dm^3/min, and the entering temperature is 27 C. The streams are mixed immediately before entering. Two reactors are available. One is a gray 200 dm^3 CSTR that can be heated to 77 C or cooled to 0 C , and the other is a white 800 dm^3 PFR operated at 27 C that cannot be heated or cooled but can painted red or black.
Note k=0.07 dm^3/mole.min at 27 C and E=20 kcal/mole.
a. Which reactor and what conditions do you recommend?
b. What conversion would be obtained if the CSTR and PFR were operated at 27 C
and connected in serious? In parallel with 5 mole/min to each ?
