1. The multiple reversible reactions * A RS and A'S 2K - R 4 K K 9 with rates -TA= 3kCA - KCR-kC, TR = 2kCA - 2kGr + kCs, ts = kCA + KCR - 2ks occur in a steady-state, isothermal, constant-v CSTR. The inlet contains pure A only at concentration Co. The residence time is t = V/u. (e) Using the results of part (c), derive an expression for the conversion, XA, in terms of rate constant k, and the residence time t. From this result, evaluate xx, in the limit in which 00 (1) Sketch (by hand) x, in terms of the variable kr. (g) Using the results of part (c), derive expressions for the overall fractional yield, O = Cr/Cao-C), and the selectivity, Y = Cr/Cs, in terms of the rate constant k, and the residence timer. From this result, evaluated and Y in the limit in which -00, (h) Sketch (by hand) and Y in terms of the variable kr
