AR (second order) (rate constant k1) A S (first order) (rate constant k2) The parallel simple elementary liquid phase reactions given above are desired to be carried out in two CSTRs of different volumes connected in series to produce the desired product R. If the initial concentration of A in the feed stream is C_Ao=2.5 mol/L, the products are not present at t=0 [C_Ro=C_So=0]. The retention time of the first CSTR is 4 minutes, and the retention time of the second CSTR is 7 minutes. Since it is known that the concentrations of the components in the first CSTR are C_A1= 1.0 mol/L, C_R1=1.0 mol/L and C_S1=0.5 mol/L; a) Calculate the k-rate constants for parallel reactions. b) Calculate the concentrations of the components (C_A2, C_R2, C_S2) in the stream leaving the second CSTR. c) Calculate the total conversion rate of A.
