化学反应速度和化学平衡原理是中学化学的重要基础理论。这方面理论学得扎实,能加深理解初中“溶解平衡”和高一硫酸、硝酸的工业生产的化工原理,并为高二学习“电解质溶液”、“络合物”等有关理论打下良好的基础。这部分教材与过去教材相比,增加了不少内容,许多化学概念学生难以掌握和应用。教材中的难点除在新课讲授时适当分散外,还可以在复习时把前后的知识连贯起来,应用归纳对比的方法,启发诱导学生分析、综合、概括所学的知识,加深对化学概念的理解,使所学的知识系统化、条理化。一、在复习化学反应速度时,要紧紧抓住活化
The principle of chemical reaction speed and chemical equilibrium is an important basic theory of middle school chemistry. In this aspect, the theory is well-founded and can deepen the understanding of the “dissolving balance” of junior high school and the chemical principle of high-sulphuric acid and nitric acid industrial production, and lays a good foundation for high school to learn about “electrolyte solution” and “complex” and other related theories. Compared with past textbooks, this part of the textbook has added a lot of content, and many students of chemistry concepts are difficult to master and apply. Difficulties in the teaching materials are not only properly dispersed during the new lesson, but also can be used to connect the knowledge before and after the review, apply the methods of induction and comparison, and inspire students to analyze, synthesize, and generalize the knowledge learned, and deepen the concept of chemistry. Understand and systematize the knowledge learned. First, when reviewing the speed of chemical reactions, we must firmly grasp the activation
