(一)分子反应动力学是当代化学与物理领域中的一门交叉学科。它从分子的微观层次出发研究基元反应过程的速率和机理,着重于从分子的内部运动和分子因碰撞而引起的相互作用来观察化学基元过程的动态学行为。所以分子反应动力学又可称为微观反应动力学。微观反应动力学是宏观反应动力学的基础。因为只有从 (A) Molecular reaction kinetics is an interdisciplinary field in contemporary chemistry and physics. It studies the rate and mechanism of the elementary reaction process from the micro-level of the molecule, and focuses on observing the dynamic behavior of the chemical elementary process from the internal movement of molecules and the interaction of molecules due to collisions. So molecular reaction kinetics can be called micro-reaction kinetics. Micro-reaction kinetics is the basis of macro-reaction kinetics. Because only from
