O(3P)原子和硅烷化学反应动力学研究
摘要:
本文报道了用流动放电-化学发光技术测定O(~3P)和硅烷化学反应速率常数.在293—413K范围内, 结果为
k=(1.05±0.36)×10~(-10)exp[(-3.06±0.10) kcal·mol~(-1) /RT] cm~3·molecule~(-1)·s~(-1)
并用过渡态理论将上述实验结果外推到200—2000 K范围内. 计算结果以三参数公式表示为:
k=7.67×10~(-19) T~(2.59) exp(-720 cal·mol~(-1)/RT) cm~3·molecule~(-1)·s~(-1).

THE KINETIC STUDY OF REACTION O(3P) AND SILANE
Abstract:
The measurement of rate constant of reaction O~3(P) + SiH_4 with discharge flow-chemiluminescence technique is presented. The Arrhenius form of the rate constant over temperature range 293--413 K is
k=(1.05±0.36)×10~(-10)exp[(-3.06±0.10)kcal·mol~(-1)/RT]cm~3·molecule~(-1)·s~(-1)
Using transition-state theory, the result was extrapolated to temperature range of 200--2000 K. The calculated dependence of the rate constant on temperature with three parameters is
k=7.67×10~(-19)T~(2.59)exp (-720 cal·mol~(-1)/RT)cm~3·molecule~(-1)·s~(-1).
