WebWhich reactor, a CSTR or a PFR, would you choose with C A 0 = 2 mol / L to achieve higher S B / A ? Compute C A and C B in the effluent from this reactor, C A f and C B f , respectively, by working with mass balances for A and B. (b). A second continuous flow reactor is to be used to reduce C A from C A f to 0.4 mol / L. Deduce that a PFR would ...
