The exothermic reaction of stillbene (A) to form the economically important trospophene (B) and methane (C), i.e.,                           A ⎯⎯→ B +C was carried out adiabatically and the following data recorded: The entering molar flow rate of A was 300 mol/min. (a)What are the PFR and CSTR volumes necessary to achieve 40% conversion for a singel reactor process.  (b)Over what range of conversions would the CSTR and PFR reactor volumes be identical? (c) What final conversion can be achieved if a 72-dm3PFR is followed in series by a 24-dm3CSTR?
