AR is being carried out in a reactor system containing two ideal CSTRs in series. Both reactors operate at 150C. The molar flow rate of A entering the first CSTR is 55,000mol/hr and the concentration of A in this stream is 6.5mol/L. The concentration of R in the inlet is 0mol/L. The fractional conversion of A in the outlet stream from the second CSTR is 0.75. This fractional conversion is based on the molar flow rate entering the first CSTR. The reaction is first order in both directions. The rate constant for the forward reaction at 150C is 1.28 h1 and the equilibrium constant based on concentration at 150C is 10.0. If the volume of the second CSTR is 10,000L, what is the required volume of the first CSTR
