Consider the following homogeneous isothermal liquid-phase parallel reactions carried out in three reactor configurations (having identical volumes and same operating temperatures), as shown in the figure.
A + B → D Rate of formation of D: r_D = k₁C_AC_B
A + B → U Rate of formation of U: r_U = k₂C_A²C_B
where D is the desired product and U is the undesired product. The inlet concentrations of A and B are the same in all three configurations (C_A0 = C_B0 = 1 mol L⁻¹). The total molar feed flow rate of A (F_A0) and that of B (F_B0) are the same in all three configurations (F_A0 = F_B0 = 10 mol min⁻¹). In configuration I, F_A0 is equally distributed among all the inlets. Similarly, in configuration III, F_B0 is equally distributed among all the inlets. Assuming plug flow behavior, at steady state, which one of the following statements is CORRECT?
