Is taking place in the gas phase in an ideal, isothermal PFR at constant total pressure. The reaction temperature and pressure are 400 K and 1 atm, respectively. At these conditions, the gas mixture obeys the ideal gas law. The rate equation isCKkCr+=−1The volume of the reactor is 1000 L, and the molar flowrate of A is 500 mol/h. The mole fraction of A in the feed stream is 0.50. At 400 K, k = 45 h-1 and KA = 50 L/mol-A. What is the fractional conversion of A in the stream leaving the PFR?
