The exothermic reaction of stilbene (A) to form the economically important trospophene (B) and methane (C), i.e., AB+C was carried out isothermally, and the following data were recorded:

The entering molar flow rate of A was 300 mol/min.

(a) What is the conversion that can be achieved in a 100-L CSTR? (b) What is the conversion that can be achieved in a 100-L PFR? (c) What conversion can be achieved if a 27-L CSTR is followed in series by a 42-L PFR? (d) What conversion can be achieved if a 27-L PFR is followed in series by a 42-L CSTR?
