A-> R(second order) (rate constant k1) A-> S (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=2.2 mol/L CRo=CSO= 0. The retention time of the first CSTR is 4 minutes, and the retention time of the second CSTR is 6 minutes. Since it is known that the concentrations of the components in the stream leaving the first CSTR are CA1= 0.9 mol/L, CR1=0.9 mol/L and CS1=0.4 mol/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.
