论文部分内容阅读
化学反应速率及化学平衡是中学化学的重要理论之一,它对中学化学各部分知识的学习有着重要的影响。考试大纲对本部分的要求是“了解化学反应速率的概念,反应速率的表示方法,理解外界条件对反应速率的影响;了解化学反应的可逆性,理解化学平衡的涵义及其与反应速率之间的内在联系;理解勒夏特列原理的涵义,掌握浓度、温度、压强等外界条件对化学平衡移动的影响”。由此可知化学反应速率及化学平衡必将是高考的重点和热点。根据教学大纲和考试大纲的要求.我们在本部分复习中必须弄清以下问题:
Chemical reaction rate and chemical equilibrium is one of the important theories of chemistry in middle school. It has an important influence on the learning of all parts of chemistry in middle school. The requirements of this part of the syllabus are “understanding of the concept of chemical reaction rate, the reaction rate of expression, understanding of external conditions on the reaction rate; understand the reversibility of chemical reactions, understand the meaning of chemical equilibrium and its reaction rate Understand the meaning of Le Chatelier principle, master the concentration, temperature, pressure and other external conditions on the impact of chemical equilibrium shift ”. This shows that chemical reaction rate and chemical equilibrium will be the focus and hot college entrance examination. According to the syllabus and the syllabus requirements we review in this section must find out the following questions:
