摘　　要：化学反应焓是物理化学学习的重点和难点,通过教学实践发现,设计生成焓与反应焓关系、燃烧焓与反应焓关系的能级图,能够简化计算过程,而且可以清楚得区别反应焓、生成焓和燃烧焓.The key and difficult points of physical chemistry may be the calculanon ot reac-tion enthalpy. Reaction enthalpy, formation enthalpy and combustion enthalpy often make thebeginners confused in the calculation process. By designing energy level diagrams, including reac-tion enthalpy, formation enthalpy, combustion enthalpy and so on, it was discovered that thosediagrams were helpful to simplify the calculation process and to clearly make a distinction aboutdifferent enthalpies above-mentioned.

关 键 词：能级图 反应焓 生成焓 燃烧焓 离子生成焓
