物理化学中关于n级反应及其半衰期的讨论

Discussion on the nth Order Reaction and Its Half-Life in Physical Chemistry

相对于积分法和微分法,由半衰期法确定反应级数的方法具有更高的可靠性和普适性。但教科书上由n级反应推导半衰期的过程却较为模糊。本文通过四种不同的方法详细探讨了n级反应及其半衰期的推导过程,有利于学生加深对n级反应及其半衰期推导过程的认识。

Comparing with integral and differential means,the half-life mean derived from nth order reaction to confirm reaction order is more reliable and universal.However,the derivation processes in textbooks are not clear.In this paper,we discussed the derivation processes of nth order reaction and its half-life in details using four different ways.It is beneficial for students to deepen the understanding of derivation processes about nth order reaction and its half-life.
