1. (25 pts) The irreversible gas-phase reaction A+2BC+D is carried out adiabatically in a PFR. Feed contains A,B, and inert in a molar ratio of 1:1:3 and enters the reactor at 40C and 1atm. Calculate the reactor volume necessary to achieve 48% conversion of A, if the volumetric flow rate is 75L/s and the reaction is 1st order with respect to A and 1st order with respect to B.
