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. Assume an initial concentration of 420 mg of A. Assume a half-life of 30 minutes if first-order kinetics are obeyed, and a depletion rate of 60 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. Assume 99% to...
