Abstract This paper reorganized the teaching content of “thermal effect in chemical reactions” in textbook published by Jiangsu Education Press in the background of nitrogen fixation, analyzed the causes of energy production in chemical reactions. Thus students understood the effects of energy on chemical reactions, and analyzed equipment optimization and condition control in process flow using energy view. Finally, students mastered core knowledge during the process of solving problems and had systematic energy view.
