作为一级反应的代表,甲酸与溴的氧化反应,自1973年Smith发表了用电动势法跟踪溴浓度随时间的变化,计算反应级数、反应速度常数和活化能的实验方法以来,已被广泛地采用于高校基础物理化学实验中。该实验具有使用仪器比较简单;可用电位差计直接测量反应进程中电势的变化,或用记录仪自动记录,操作简便;又可用计算机处理数
As a representative of the first-order reaction, the oxidation reaction of formic acid and bromine has been widely published since Smith published the electromotive force method to follow the variation of bromine concentration over time and calculate the reaction order, the reaction rate constant and the activation energy since 1973 Used in basic physics and chemistry experiment in colleges and universities. The experiment has the use of equipment is relatively simple; Potentiometer can be used directly to measure the potential changes in the reaction process, or automatically recorded with a recorder, easy to operate; also available computer processing
