化学反应速率的过渡态理论

THE TRANSITION STATE THEORY OF CHEMICAL REACTION RATE

由海森堡运动方程证明了过渡态几率稳定定理.假设化学反应均经过过渡态,由此定理推导了化学反应的微观速率常数.再假设反应的始志处于热平衡,由微观速率常数推导了宏观速率常数.

The elementary chemical reactions are assumed to pass via the transition states.From the Hersenberg equation of motion,it is proved that the probabilities of transition states are stationary.From this theorem and the Hersenberg equation of motion there are derived the micro and macro reaction rate constants of both the direct and complex models of reactions.
