化学反应活化能是化学动力学中一个极其重要的概念。不仅它对反应速率的影响是举足轻重的,而且活化能的问题又是相当复杂的:其一,不同化学反应有不同的活化能;其二,同一化学反应的活化能也有各种不同的理解,其三,从理论上要严格计算某一反应的活化能所遇到的困难是难以想象的。因此,1889年,阿累尼乌斯(Arrhenius)首先提出活化能的概念后,在国际上围绕什么是活化能的问题曾辨论了几十年,先后提出
Chemical reaction activation energy is an extremely important concept in chemical kinetics. Not only its impact on the reaction rate is significant, but the problem of activation energy is quite complicated: First, different chemical reactions have different activation energies; second, there are different understandings on the activation energy of the same chemical reaction, Thirdly, it is unimaginable that the difficulties encountered in theoretically calculating the activation energy of a certain reaction should be unimaginable. Therefore, Arrhenius first proposed the concept of activation energy in 1889 and argued for decades around the issue of what is activation energy. He has proposed
