本文对如下几个问题作一些讨论:(1)氧化还原反应的速度和其电位差ΔΦ值的大小无关;(2)反应活化能;(3)对氧化还原反应机理作一粗略介绍。一、氧化还原反应的速度和ΔΦ值无关氧化还原反应不像酸碱反应那样可在瞬间完成。氧化还原反应进行的速度很不相同,有的进行的较快,许多氧化还原反应进行得很慢。两个半反应的电位Φ的差值,可预测所给的 This paper discusses some of the following issues: (1) the rate of redox reaction and its potential difference ΔΦ value has nothing to do; (2) reaction activation energy; (3) on the redox reaction mechanism for a rough introduction. First, the rate of redox reaction and ΔΦ irrelevant Redox reaction is not as acid-base reaction can be completed in an instant. Redox reactions proceed at very different rates, some proceed faster, and many redox reactions proceed slowly. The difference between the two half-reaction potentials φ can be predicted as given
