AR (second order) (rate constant k1), AS (first order) (rate constant k2) Parallel liquid phase reactions are carried out in two CSTRs connected in series to produce R and S. In the feed, CAo =2.2mol/LCRo=CSO=0. The first CSTR has a retention time of 3.0 minutes, and the second CSTR has a retention time of 11 minutes. Since it is known that the concentrations of the components in the first CSTR are CA =0.7mol/L,CR=0.8mol/L and CS=0.7mol/L; a) Calculate the k-rate constants for parallel reactions. b) Calculate the concentrations of the components in the stream leaving the second CSTR. c) Determine A's total conversion rate
