高中化学必修二ppt | 21 化学反应速率的影响因素
前言：以下是本人林含键课堂教学课件分享（前面已分享了必修二20个课件和必修一55个课时的课件合集【高中化学必修一ppt】55 期末模拟卷讲评）。课件获取方式请看文末指引（禁止未授权的二次传播或商用，原创不易，感谢理解！
这一节是化学反应速率的影响因素，在初中接触催化剂的基础之上，进一步用“变量控制法“的实验要求来探究浓度、温度的影响，拓展学习压强对气体反应的影响，学习实验活动7中的反应。
回顾上节课学习的化学反应速率的内容。
通过变量控制的实验方法，探究反应温度、反应物浓度对速率的影响。
反应温度的影响。

总结其他因素，并学会应用和分析。
教材练习
实验活动7中涉及的反应较为重要，仔细讲解。
浓度对反应速率的影响这个实验的设计，比较经典，特别是加入的水的用量，是一个常考的实验题。
