Laboratory Teaching Results and Discussions of“Determination of Kinetic Constants of the Hydrolysis Reaction of trans/cis-[Co(en)_(2)Cl_(2)]Cl Complexes”

主要介绍厦门大学专门为"化学拔尖计划"学生个性化培养"量身定制"并经10年教学实践的"trans/cis-[Co(en)2Cl2]Cl配合物水解反应动力学常数测定"实验教学实施结果及探讨内容。引导学生以动力学实验数据和实验结果为依据,讨论和探究了介质、温度等对trans/cis-[Co(en)2Cl2]Cl配合物水解反应的影响,让学生直观认识顺-反异构体配合物的结构不同,所表现的水解反应动力学的差异,了解结构决定性质的涵义,培养学生归纳、总结、分析、判断的能力以及批判性思维能力。

This paper mainly introduces the laboratory teaching implementation results and discussions of“determination of kinetic constants of the hydrolysis reaction of trans/cis-[Co(en)2 Cl2]Cl complexes”,which has been carried out for 10 years and particularly designed for top-talented chemistry-majored students at Xiamen University.Students were guided to discuss and explore the effects of reaction medium and temperature on the hydrolysis reaction of trans/cis-[Co(en)2 Cl2]Cl,based on the dynamic experimental data and results.In light of this,students could directly understand the differences in the hydrolysis reaction kinetics behavior of trans/cis isomer with different structure,and the meaning of“structure decides the nature”.Their ability of induction,summary,analysis,judgment and critical thinking can be cultivated.
