PA With all reactions first order and ir-reversible. a) Find concentrations for all species in a CFSTR. b) Find concentrations for all species in a PFR. N = Naphthalene, NQ = Naphthenoquinone PA = Phthalic Anhydride k1, k2 , k3, & k4 are all rate constants.
Calculate the amount of mono, di & Trichlorobenzene produced by 10,20,30,90 & 95%. Benzene conversion in the chlorination of Benzene for the parallel and consecutive reaction scheme. The reactions are being carried out at 328º k in a constant volume batch reactor. The values of ratio of rate constants are k k2 0.125 and 3 0.042 k1 k1 at the above temperature.

A petrochemical plant owner wish to produce B in the reaction A B in a continuous reactor at 2 lit / min with CAO = 4 moles/lit. However, he find that there is second reaction A C which can also occur. He find that both reactions are first order and irreversible with k1 = 0.5 min-1 and k2 = 0.1 min-1. Find ,V, CB, SB and YB for 90% conversion of A.
