全日制十年制学校高中化学课本第一册第五章P.158页压强对平衡的影响[实验5—5],是中学化学的一个重要的难点实验。近年的各种杂志虽已刊登了不少这方面的研究文章,在这里还想谈点个人的粗浅看法与大家共同探讨:第一,怎样从理论上对此实验进行分析?第二,这个实验的正确性究竟如何?第三,怎样对该实验进行一些改进,以提高其演示效果?现就压强对N_2O_4(?)2NO_2平衡移动问题讨论如下:
The effect of pressure on the balance [Experiment 5–5] is an important difficulty experiment for middle school chemistry in full-time, 10-year high school chemistry textbooks. Although various magazines in recent years have published many research articles in this area, here we would also like to talk about some people’s superficial views together with everyone: First, how to theoretically analyze this experiment? Second, this experiment What is the correctness of this? Third, how do we improve the experiment to improve its demonstration effect? Now we discuss the pressure shift on the equilibrium movement of N_2O_4(?)2NO_2 as follows:
