【摘要】 本文通过大量的实验得出:离子强度调节剂相同时,被研究反应的表观速度常数 Kapp 随离子强度Ⅰ增大而增大;离子强度相同时,Kapp 按NaClO₄、NaNO₃、NaCl、Na₂SO₄这一离子强度调节剂的顺序递增.并园满地解释了离子强度调节剂的阴离子通过静电效应促使前驱配合物的形成阶段加速,是被研究反应表观速度常数 Kapp 增大的主要原因.更多还原

【Abstract】 This article sums up the following two principles from a series of experimental data:when the same ionic strength is used as a regulator the apparent rate constant Kapp of the reaction studied increases with the increase of ionic strength I when the ionic strength is the same Kapp will increase to the order of NaClO₄,NaNO₃,NaCl,Na₂SO₄.The anion of the ionic strength regulator through electrostatic effect causes the increase of step acceleration in the formation of precursor complex and thus becomes the major cause of the increase of the apparent rate constant of reaction studied.更多还原
