The aqueous decomposition of A was studied in an experimental mixed flow reactor (CSTR)from which the following results are obtained at steady-state conditions:CA, feed [mol/litre] 2.0 2.0 2.0 1.0 1.0 0.48 0.48 0.48CA, exit [mol/litre] 0.65 0.92 1.0 0.56 0.37 0.42 0.28 0.2Space-time seconds 300 240 250 110 360 24 200 560What space-time is required to achieve 75 % conversion of A in the feed ($C{A0} = 0.8$ mol/litre)in:a) a plug-flow reactor (PFR)?b) a mixed-flow reactor (CSTR)?(16)(4)Hint 1 - in
