当用单分子反应来研究气固表面多原子分子振动能量的传递过程时,其规律如下: (1)气固传能效率随温度升高而下降,自然这是相对于玻尔兹曼平衡分布而言的。 (2)气固反应活化能小于气相反应活化能。通常用气固碰撞矩阵表征气固传能过程。
When using single molecule reaction to study the vibrational energy transfer process of polyatomic molecules on gas-solid surface, the rules are as follows: (1) The efficiency of gas-solid energy transfer decreases with increasing temperature, which is naturally relative to the Boltzmann equilibrium distribution In terms of. (2) The activation energy of gas-solid reaction is less than the activation energy of gas phase reaction. Gas-solid collision matrix is usually used to characterize the process of gas-solid energy transfer.
