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). -
