Question: Parallel simple elementary liquid-phase reactions AR (second order) (rate constant k1) and AS (first order) (rate constant k2) are desired to be carried out in

Parallel simple elementary liquid-phase reactions AR (second order) (rate constant k1) and AS (first order) (rate constant k2) are desired to be carried out in series-connected CSTRs with different volumes to produce the desired product R. The initial concentration of A in the feed stream is CAo=2.5 mol/L and there are no products present in the environment at t=0 [CRo=CSO=0]. The residence time of the first CSTR is 4 minutes and the residence time of the second CSTR is 7 minutes. It is known that the concentrations of the components in the first CSTR are CA1=1.0 mol/L, CR1=1.0 mol/L, and CS1=0.5 mol/L. Given this information: a) Calculate the k-rate constants for the parallel reactions. b) Calculate the concentrations of the components (CA2, CR2, CS2) in the stream leaving the second CSTR. c) Calculate the overall conversion rate of A.
