Consider two plug flow reactors operated isothermally and isobarically. The following elementary gas phase reaction 2A + B takes place in the PFRs. The fresh feed - flows at 150 mol/s and 5 m/s and it contains A=80% and the balance is inert. The rate constant at 400K is given by k=0.05 mmolls. The volume of the first PFR is 6 m and it receives two thirds (2/3) of the fresh feed. The volume of the second PFR is 10 m and it receives the remaining fresh feed. The two PFRs operate at 400K i- What is the final conversion of A if the two reactors are connected in parallel? (6 points)
