论文部分内容阅读
化学反应速率和化学平衡是中学化学的主干知识,是每年高考的必考内容,而其中化学反应速率知识是学习化学平衡知识的基础,只有了解化学反应速率才能理解化学平衡原理。那么,怎样学好这部分内容?笔者从自己的教学实际及教材的特点出发,对外界条件对反应速率的影响作以阐释。从教材内容来看,本部分内容有两大主线:一是从定性的角度分析化学反应速率及影响因素,二是从定量
Chemical reaction rate and chemical balance are the backbone knowledge of secondary chemistry, which is the compulsory part of the annual college entrance examination. The knowledge of chemical reaction rate is the basis for learning chemical equilibrium knowledge. Only the chemical reaction rate can understand the principle of chemical equilibrium. So, how to learn this part of the content? The author from their teaching practice and the characteristics of textbooks, the external conditions on the reaction rate to explain. From the teaching material content, this section has two main lines: First, from a qualitative point of view of chemical reaction rate and the impact of factors, the second is from the quantitative
