分光光度法研究可逆反应动力学过程

Spectrophotometric Method for Kinetics of Reversible Reaction

动力学实验是物理化学实验教学中的重要组成部分。利用分光光度法研究酚酞-NaOH体系可逆动力学反应过程,实验结果表明环境温度对该实验反应趋势影响不大,仅使用分光光度计一种仪器即可完成实验教学。该实验所用试剂毒性低、用量少,符合绿色化学实验理念。

Kinetics is an important part of physical chemistry laboratory teaching. In this article, we present a spectrophotometric method for study of the reversible kinetic reaction process of phenolphthalein-NaOH system. The ambient temperature has little influence on the experimental reaction, and the spectrophotometer is the only required instrument for carrying out this experiment. All reagents used are in small amount and low toxic, which is in accordance with the green chemistry concept.
