(ii) Compare and contrast how first-order reaction kinetics and zero-order reaction kinetics differ in terms of the depletion of a reactant A in a chemical reaction using the following information. Assume an initial concentration of 600 mg of A. Assume a half-life of 30 minutes if first-order kinetics are obeyed, and a depletion rate of 120 mg/hour if zero-order kinetics are obeyed. Use a clearly drawn graph(s) to determine which rate will result in complete depletion of A over the shortest time. [12 marks] Assume 99% to be complete depletion of A
