化学原理中化学热力学的教学设计与思考

Teaching Design and Thinking about Thermodynamics in Chemical Principles

本文就化学热力学的教学过程中出现的知识点进行了分析,通过和物理学中的热力学过程进行比较,可以让学生更好理解、应用一些概念。另外对化学热力学过程进行直观的分析,使其贴近实际,还对应用吉布斯自由能变判断自发反应方向问题进行分析,让学生理解反应的标准吉布斯自由能变所代表的含义,适用的条件。通过理清这几个问题有助于学生化学热力学的学习。

This paper analyzes the knowledge points in the teaching process of chemical thermodynamics.By comparing with the thermodynamic in physics,students can understand and apply concepts of thermodynamics.In addition,the chemical thermodynamic process is analyzed intuitively to make it close to the reality.The application of Gibbs free energy change to judge the direction of spontaneous reaction is also analyzed,so that students can understand the meaning of the standard Gibbs free energy change of reaction and the applicable conditions.Which is helpful for students to study chemical thermodynamics.
