新课标实施以来,一项较大的变化就是化学由定性描述走向定量研究,其中体现之一就是四大平衡常数的引入给化学反应原理增加了有力的分析依据。“用数据来说话”让化学变得富有活力,同时也带来了一系列思维的发展与能力的考查,所以从一定意义上讲,掌握了四大平衡常数,就握住了一把解决化学问题的金钥匙。一、四大平衡常数的比较 Since the implementation of the new curriculum standard, a major change has been the shift of chemistry from qualitative description to quantitative research. One of the manifestations is that the introduction of the four equilibrium constants adds a powerful analytical basis to the chemical reaction principle. “The use of data to speak” makes chemistry more dynamic, and it also brings with it a series of thinking developments and competencies. Therefore, in a certain sense, mastering the four equilibrium constants, we have grasped a The golden key to solving chemical problems. Comparison of one and four major equilibrium constants
