The first-order irreversible reaction takes place isothermally in the gas phase with a reaction rate: = in a CSTR reactor. A 50% conversion for pure A is currently achieved by entering the reactor at 20 atm. There is no pressure drop in the CSTR.

It is proposed to place a PBR reactor in series with the CSTR. The PBR contains 50 kg of catalyst with a particle size of 0.2 mm and a porosity of 40 %. For the pressure drop across the PBR use = 0.018 1 . Consider Determine:

a) The conversion at the outlet of the second reactor

b) The pressure at the outlet of the PBR

k/F_A0 = 10^-3/atm*kg_cat
