A gaseous feed of A and B, with initial parameters of 2000 L/min flow, 50 mol/L of A, and 25 mol/L of B, will be converted to gaseous product J in a plug flow reactor that is operating under isothermal and isobaric conditions. The reaction is represented by: 0.4A+B The rate of destruction of A, in unts of mol 1 min1, is first order with respect to A, half (0.5) order with respect to B, and the rate constant is 10 L0.5 mol0.5 min1. Estimate the plug flow reactor volume, in liters, that is needed to achieve a conversion of 99% of the limiting reactant to product . Express your answer as an integer, Le 123.57 would be input as 124. Hints: Determine the limiting reactant. It may help to re-express your reaction so that 1 mole of the limiting reactant is reacting, if the reaction is not already set up in this fashion. Remember the design equation for a PFR, and express the equation in terms of the limiting reactant-this includes using the rate of reaction of the limiting reactant. Develop a stoichiometric table. Remember the definition of concentration for a flowing reactor. Remember that gases can expand or contract, depending on the reaction.
