摘　　要：用热力学方法推导了选择标准浓度c^(■)(1 mol/dm^(3))和标准压力p^(■)(10Pa)两种热力学标准状态时过渡态理论的速率系数表达式,及对于生成活化络合物反应的标准摩尔活化热力学函数在这两种热力学标准状态时的相互关系,这些结果对常见物理化学教材过渡态理论部分忽略之处给予了补充,并用研究案例说明了其应用,有利于物理化学过渡态理论的教与学和加深其应用的理解。The rate coefficient expressions of the transition state theory are derived by using the thermodynamic method when two thermodynamic standard states of standard concentration c^(■)(1 mol/dm^(3))and standard pressure p^(■)(10Pa)were selected.For the reaction of generating activated complex,the interrelationship of the standard molar activation thermodynamic function in these two thermodynamic standard states are obtained.These results supplemented the neglected part of transition state theory in common Physical Chemistry textbooks,and illustrated its application with research cases,which are beneficial to the teaching and learning of transition state theory in Physical Chemistry and deepening the understanding of its application.
