The rate constant for the reactions of oxygen atoms with nitric oxide and silane were determined using a discharge flow apparatus. A microwave discharge through O2N2 and Ar was used to produce oxygen atoms. The rate constant for the reaction O + NO + Ar was determined to be (7.0+0.4) x 10^32 cm^6 s^-1 and is in good agreement with previous measurements. Modeling of the O +SiH₄ reaction was performed to determine the correction to the rate constant due to secondary reactions. The rate constant for the reaction O + SiH₄ was determined to be (3.3 +/- 0.3) x 10⁻¹³ cm³ s⁻¹ and is in good agreement with previous measurements. Previous literature, thermochemistry, and spin conservation were used to determine a probable mechanism for the O + SiH₄ reaction.
