盖斯定律在求算反应热中的应用,属于高考的新增热点,但传统的化学方程式叠加法,计算起来费时且易算错。本文通过构建数学模型,采用待定系数法能快速解决学生会而不对的困境,具有很强的实用性。
The application of Gass’ law in the calculation of reaction heat is a new hot spot for the college entrance examination. However, the traditional chemical equation superposition method is computationally time-consuming and error-prone. This paper builds a mathematical model and adopts the undetermined coefficient method to quickly solve the dilemma of the student union. It has strong practicality.
