1. The desired liquid-phase reaction A+B → P+R with dep = dCR = k, C1-5 C03 dt dt is accompanied by the undesired side reaction ds A+B+S+T with det kz C 0-5 CB18 dt dt Order the contacting schemes given below for product distribution from the most favorable to the least favorable. Contacting schemes: (1) A plug flow reactor (2) A plug flow reactor with side streams of B (3) A plug flow reactor with side streams of A (4) A mixed flow reactor. (4)
