在分子与分子之间发生碰撞时,如果分子的动能足够大,当超过一定的阈值E时,分子碰撞就会发生化学反应.然而气体分子化学反应速率是受到一定因素影响的,诸如分子数密度n、温度T以及速度V.日本学者Sagara于上世纪70年代曾对分子数密度n和温度T对反应速率的变化做了深入的探究.主要是在此基础上利用二粒碰撞机理论对速度以及温度和速度的共同作用来研究反应速率的变化情况.
When a molecule collides with a molecule, if the kinetic energy of the molecule is large enough, a chemical reaction will occur when the molecule collides with a certain threshold E. However, the rate of gas molecule chemical reaction is affected by factors such as molecular number density n, temperature T and velocity V. Japanese scholar Sagara made in-depth study on the change of reaction rate by molecular number density n and temperature T in the 1970s, mainly on the basis of the theory of two-particle collider And temperature and speed of the interaction to study the reaction rate changes.
