本文从化学反应自由能与反应进度的关系出发,导出了化学反应平衡点受温度和压力影响的关系式。然后运用电子计算机(Apple-Ⅱ)对三个不同反应类型进行计算和作图,阐述了化学反应平衡点随反应条件的变化而移动的规律。本方法对于研究化学平衡具有普遍的意义。 Based on the relationship between the free energy of chemical reaction and the progress of reaction, this paper derives the relationship between the chemical reaction equilibrium point and temperature and pressure. Then, three different reaction types were calculated and mapped by using computer (Apple-Ⅱ), and the rule that chemical reaction equilibrium shifts with the reaction conditions was expounded. This method has universal significance for the study of chemical equilibrium.
