摘　　要：能斯特方程是电化学中一个非常重要的关系式,体现了电对电极电势与溶液中离子浓度、气体分压和介质条件的关系,也是教学过程中的重点和难点,深刻理解和熟练应用该方程尤为重要,从而为后续课程的学习奠定基础。本文将反应商和能斯特方程相结合,通过具体实例讨论了电极电势、电动势与反应商之间的关系,并就能斯特方程的相关解题思路与技巧进行了阐述,以期促进对能斯特方程的理解和应用。Nernst equation is a very important relationship in electrochemistry, which reflects the relationship between the potential of electric pair electrode and ion concentration, gas partial pressure and medium conditions in solution. It is also the key and difficult point in the teaching process. It is particularly important to deeply understand and skillfully apply the equation, so as to lay a foundation for the study of subsequent courses. The reaction quotient was combined with Nernst equation, the relationship between electrode potential, electromotive force and reaction quotient were discussed through specific examples, and the relevant problem-solving ideas and skills of Nernst equation were expounded, in order to promote the understanding and application of Nernst equation.
