The exothermic reaction of stillbene (A) to form the economically important trospophene (B) and methane(C), that is, A → B+ C was carried out adiabatically and the following data recorded:

The entering molar flow rate of A was 300 mol/min.
1. Calculate the batch reactor (BR) times to achieve 40% and 80% conversion when 400 moles of A are charged to a 400 dm³ reactor.

2. What are the PFR and CSTR volumes necessary to achieve 40% conversion?

3. Over what range of conversions would the CSTR and PFR reactor volumes be identical?

4. What is the maximum conversion that can be achieved in a 105-dm³ CSTR?

5. What conversion can be achieved if a 72-dm³ PFR is followed in series by a 24-dm³ CSTR?

6. What conversion can be achieved if a 24-dm³ CSTR is followed in a series by a 72-dm³ PFR?

7. Plot the conversion and rate of reaction as a function of PFR reactor volume up to a volume of 100 dm³.
