The elementary gas phase reaction (A <--> 2B) is to be carried out in an adiabatic CSTR. The feed which is at a temperature of 27oC, consists of 80% of A and the remainder inerts. The volumetric flow rate entering the reactor at this temperature is 100 l/min. The concentration of A in the feed at 27oC is 0.5 mol/liter. For 80% of the adiabatic equilibrium conversion, calculate the required reactor volume.

DATA:

CpA=12 J/mol.K; CpB=10 J/mol.K; CpI=15 J/mol.K
