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: 0.4 A + B -> J. The rate of destruction of A, in units of mol L-1 min-1, is first order with respect to A , half (0.5) order with respect to B, and the rate constant is 10 L0.5 mol-0.5 min-1. Estimate the plug flow reactor volume, in liters, that is needed to achieve a conversion of 99% of the limiting reactant to product J. Express your answer as an integer, e.g. 123.57 would be input as 124.
