PS1B -化学反应


PS1B - Chemical Reactions In this video Paul Andersen explains how chemical reactions progress as bonds are broken and reformed reformed. He explains the difference between changes in state and changes in molecules. He discussed collision theory and explains why increases in temperature and concentration can increase reaction rates.

下一代科学标准物理科学学科核心理念1B:化学反应
在这段视频中,保罗·安徒生解释了化学反应是如何进行的,化学键被打破,重新形成。他解释了状态变化和分子变化之间的区别。他讨论了碰撞理论,并解释了为什么温度和浓度的增加会增加反应速率。
