摘　　要：本文讨论了气相反应的kc、kp与其活化能Ea,c和Ea,p之间的关系,及在对行反应中二种活化能与反应热力学能变、焓变之间的关系。通过误差分析论证,我们在教学中提出对Ea,c和Ea,p两种活化能应注意区分。Relationship between rate coefficient （kc or kp） and activation energy （Ea,c or Ea,p） as well as some relations of them concerning to thermodynamics have been discussed. Accordingly, based on the discussion and an analysis on relative error of the activation energy being obtained from general experiments, we suggest that the activation energies, Ea,c and Ea,p, should be well distinguished in teaching.
