Currently the elementary liquid phase reaction A + B -> R + S is conducted in in a PFR using CA0=CB0 = 2 mol/L and conversion is 85%. Management has asked to use an increase production of the 85% product. Currently available is an MFR that is five times the volume of the PFR.

(a) If we want add the MFR in series to the PFR, by what percentage could we increase output of the 85% conversion product and in which order should the reactors be placed?

(b) If instead of using the reactors in series, if we were to add the MFR in parallel with the existing PFR, now much would the output of 85% conversion product be increased?

(c) Which configuration should you recommend?
