1. The multiple reversible reactions 26 R K RS and AS K k with rates - = 3kCA - KCR-kCs, PR = 2kCA - 2kCr+kCs, rs = kCA + KCR - 2kCs = occur in a steady-state, isothermal, constant-v CSTR. The inlet contains pure A only at concentration Cao. The residence time is t = V/v. (1) Using the results of part (e) and (g), express the overall fractional yield, O = CR/C10-), and the selectivity, Y = CR/C5, in terms of the conversion x . From this result, evaluate o and Y in the limit in which XA - XA () Sketch (by hand) and Y in terms of the conversion xx (k) A CSTR has Da = (-ro)V/FAo = 3. Find the conversion, xx, that can be achieved and the values of D and Y
