Experimental data for the gas-phase catalytic reaction A + B C is shown below. The limiting step in the reaction is known to be irreversible, so that the overall reac- tion is irreversible. The reaction was carried out in a differential reactor to which A, B, and C were all fed.

(e) At what conversion are the number of A and C sites equal? (Ans.: X = 0.235) (f) What catalyst weight is necessary to achieve 90% conversion of A for a stoichiometric feed and flow of A 2 mol/s? (Ans.: W = 8.9 g-cat) If necessary, feel free to use none, any, or all of the following parameter values: KA = 4 atm-', Kc = 13 atm-', Ki = 10 atm-1 = k = 2.5 mol 2 atm g-cat.s =
