从高考命题趋势看,化学平衡问题是热门考题类型,本文通过对近些年高考在这方面的考点分析,得出了高频考点,这样在复习时更有针对性,很显然要把握勒夏特列原理和平衡常数,由此展开平衡条件对化学平衡题型的制约的探讨,通过实际题型分析思考了一些在学习中应注意的事项。 From the trend of college entrance examination propositions, the issue of chemical balance is a hot topic type. This paper analyzes the test sites in the college entrance examination in this area in recent years and draws a high-frequency test point. This makes it more specific when reviewing, and it is obviously necessary to grasp Le Xia. The special principle and the equilibrium constants are used to explore the constraints of the equilibrium conditions on the chemical equilibrium question types, and some issues that should be noted in the study are considered through the actual question type analysis.
