摘　　要：通过对阿果尼乌斯公式二边直接时Ｔ微分．讨论了ｄＫ／ｄＴ与Ｅａ及Ｔ的关系．得出了在通常情况下，温度升高时，尽管反应的活化能越大．起点温度越低，反应速度常数增大的倍数就越大，但速度常数随温度的变化率却越小．In this peper,the relationship between dK/dT、Eα and T is discussed by differentiating Arrhenius equation.It is concluded that usually,when the temperature rises,althrough the reaction speed contant is greater with a greatcr activation energy and a lower starting temperature,but change rate of speed constant with temperature is smaller.

关 键 词：速度常数 活化能 温度 物理化学 化学反应
