The elementary irreversible organic liquid-phase reaction A+B --> C is carried out adiabatically in a flow reactor. An equal molar feed of A and B enters at 27oC the reactor. The volumetric flow rate is 2 dm3 /s and CA0 = 0.1kmol/m3

a.) Calculate the PFR and CSTR volumes necessary to achieve 85% conversion.

b.) What is the maximum inlet temperature on could have so that the boiling point of the liquid (550K) would not be exceeded even for complete conversion?

c.) Plot the conversion and temperature as a function of PFR volume (i. e., distance down the reactor)

d.) Calculate the conversion that can be achieved in one 500dm3 CSTR and in two 250dm3 CSTRs in series.
