The adiabatic exothermic irreversible gas-phase reaction, 2A+B C, is to be carried out in a flow reactor for an equimolar feed of A and B. A Levenspiel plot for this reaction is shown below: so0,000 400,000 Es (m) 300,000 -TA 200,000 100,000 0.6 0.9 a) What PFR volume is necessary to achieve 50% conversion? b) What CSTR volume is necessary to achieve 50% conversion? c) What is the volume of a second CSTR added in series to the first CSTR (Part b) necessary to achieve an overall conversion of 80%? d) What PFR volume must be added to the first CSTR (Part b) to raise the conversion to 80%? e) What conversion can be achieved in a 6 x 10 m' CSTR? In a 6 x 10 m' PFR?
