化学动力学与化学热力学之间的联系

物理化学建立的初期,就注意到反应速率与热力学量的联系;质量作用定律就是从化学动力学和化学热力学两个角度总结出来的结果。Eyring的绝对速率理论(过渡状态理论)利用活化络合物与反应物的标准熵变、标准焓变来计算反应速率常数。1922年Dc Donder把不可逆过程热力学用于化学反应,他定义亲和函数A,而A与反应速率v的关系是Av>0;这只表

CONNECTION BETWEEN CHEMICAL KINETICS AND CHEMICAL THERMODYNAMICS

The rate at which a chemical reaction reaches equilibrium is directly proportional to the chemical affinity, i.e. the function of the mean affinity. The final formula derived is where v is the reaction velocity, is the chemical affinity introduced by Lewis, and K, is a constant related to temperature.
