The residence-time distribution is tabulated below for a flow reactor that has a feed rate of 16.2 ft3/min. Under the feed conditions (cAf = 0.02 lbmol/ft? and CBF 2.34 Ibmol/ft3) the reaction A + B kic r = k1CA is essentially first order in the concentration of A and the rate constant is 0.23 min-1 at the temperature of the reactor. Determine the effluent concentration of reactant A when the total feed to the reactor is 16.2 ft3/min.
