Consider the liquid phase reactions shown in the following schematic diagram carried out in a plug flow reactor at steady state. A+B R (Desired) k₁ S (Undesired) TR = kCC and rs = k₁₁₁₁₁ By keeping the reaction system isothermal, the yield of the desired product can be maximized by maintaining. a) Low concentration of A and high concentration of B b) High concentration of A and high concentration of B c) Low concentration of A and low concentration of B d) High concentration of A and low concentration of B
