A system of three parallel reactions (Trambouze and Piret, 1959) involves the reaction scheme below. The reactions are zero-order, first-order, and second-order respectively, with k,-0.025 mol/L-min. k,-0.2min-1, and k3 = 0.4 L/mol-min, and the initial concentration of Ca-1 mol/L. Use the attainable region algorithm to find the reactor network that maximizes the selectivity
