A liquid feed stream with concentration CA0=2 mol/L is to be converted by the following reaction A---->R with - rA = kCA and k = 0.4min -1 at 320 K The volumetric flow rate is 2.5 L/min and temperature and pressure are kept constant at 320 K and 1 atm, respectively. Previously two CSTRs in series with each reactor having a volume of 25 L were used. a) Find the total conversion. b) Recently it is proposed to use two CSTRs in series, but one reactor has a volume of 10 L and the other has a volume of 40 L. Thus the total volume (50 L) will be the same. Which arrangement -reactor with a volume of 10 L followed by a reactor with a volume of 40 L or vice versa- will give the highest conversion?
