Kinetics of the gas phase reaction of SnO with O2
The gas phase reaction of SnOg with O2 was studied behind reflected shock waves at temperatures between 1700 and 2300 K and pressures around 100 kPa by applying atomic resonance absorption spectroscopy for time-resolved measurements of O atoms at 130.6 nm. The source of gas phase SnOg were SnO nanoparticles which rapidly evaporate behind the reflected shock wave in a few microseconds. For the reaction SnOg+O2→SnO2,g+O a rate coefficient of k1=1014.78±0.19 × exp(−23530±840K/T)cm3 mol−1 s−1 was determined for the temperature range of the present experiments.
