近几年各地高考化学卷中都出现了“化学反应速率及化学平衡”内容的试题。从整体上看,题型及难度与以往相比差异不大,但解答此类试题的能力素质要求有所上升,对分析问题能力、应用理论的能力的要求都较高。尤其加强了对化学反应速率计算及其影响因素和化学平衡常数计算及其影响因素的考查。现结合近几年高考试题对此进行点拨。
In recent years around the chemical examination in the entrance examination have appeared “chemical reaction rate and chemical equilibrium ” content of the test. On the whole, the types and difficulty of the questions are not much different from those in the past. However, the ability and quality requirements for answering such questions have risen, and the requirements for the ability to analyze problems and the ability to apply the theories are high. In particular, the calculation of the chemical reaction rate, its influencing factors, and the calculation of the chemical equilibrium constants and its influencing factors are strengthened. In recent years, the college entrance examination questions are conducted on this point.
