💡 Solution & Explanation

For reactions with order less than 1, the integrated rate law allows the reactant concentration to reach zero in a finite time. For reactions with order ≥ 1, the concentration approaches zero asymptotically, meaning the theoretical time of completion is infinite. This is a mathematical property of their kinetics, not simply because they are "too slow or too fast". Therefore, correct answer is C.
