具有相同简单级数的不同反应类型的半衰期公式——以二级反应和三级反应为例

Half-Life Formulas of Second-Order Reaction and Third-Order Reaction

化学反应的半衰期公式不仅与反应级数有关，而且与反应类型相关。具有相同简单级数的不同类型反应的半衰期表达式也往往不一致。对具有简单级数反应的半衰期表达式进行了分析，重点讨论了不同类型的二级反应和三级反应半衰期表达式的特点及其他们之间的内在联系和区别。

Half-life formulas of chemical reactions not only relate with the order of reaction, but also connect with the type of reaction. Chemical reaction with the same simple order and different type may have the different half-life formulas. In this paper, half-life formulas of chemical reactions with simple order is discussed, focusing on the feature of half-life formuias of different type of chemical reactions with a second order and a third order, as well as the relationship among them.
