P2-43 The exothermic reaction of stillbene (A) to form the economically important trospophene (B) and methane (C), i.e., AB+C was carried out adiabatically and the following data recorded: X 0 0.2 0.4 0.45 0.5 0.6 0.8 0.9 - (mol/dm-min) 1.0 1.67 5.0 5.0 5.0 5.0 1.25 0.91 The entering molar flow rate of A was 300 mol/min. (a) What are the PFR and CSTR volumes necessary to achieve 40% conversion? (VPFR = 72 dm, VcSTR 24 dm) (b) Over what range of conversions would the CSTR and PFR reactor volumes be identical? (c) What is the maximum conversion that can be achieved in a 105-dm CSTR? (d) What conversion can be achieved if a 72-dm PFR is followed in series by a 24-dm CSTR? (e) What conversion can be achieved if a 24-dm CSTR is followed in a series by a 72-dm PFR? (f) Plot the conversion and rate of reaction as a function of PFR reactor volume up to a volume of 100 dm a a
