【摘要】 本文通过一系列实验数据总结出下述规律:顺式—三溴乙醇胺双乙二胺合钴（Ⅲ）cis—[Co（etaH）（en）₂]Br₃与[Fe（CN）₆]^4-间外界电子转移反应的表观速度常数K_ob（?）d,随溶液的pH值增大而增大,随离子强度I减小而增大和随介电常数D减小而增大。上述事实说明,配体加合质子作用、离子对水化作用和溶液静电效应。是被研究反应K_ob（?）d变化的主要原因。更多还原

【Abstract】 This article sumarizes the following principles from a series of experimental data:under equal conditions the apparent rate constant kobsd of the outer—sphere electron—transfer reaction beween Cis—[Co（etaH） （en）₂]Br₃ and [Fe（CN）₆]^4- increases with an inprease in pH of solution, it increases with the decrease in ionic strength I and it increases with the decrease of the effection in dielecric constant D.and it expounds the principle of pH,ionic strength I and dielectric constant D by using effect of protonation of ligands, aquation of ion pair and electostatic effect of sloution.更多还原
