Shock tube study of the reaction of H atoms with SnCl4

The reaction of H atoms with SnCl4 was studied behind reflected shock waves at temperatures between 1020 and 1360 K and pressures around 150 KPa by applying atomic resonance absorption spectrometry for time-resolved measurements of H atoms at the Lα line. The thermal decomposition of ethyl iodide (C2H5I) served as the H-atom source. For the reaction SnCl4 + H → SnCl3 + HCl a temperature-independent rate coefficient of k1 = 3.5 ± 0.5 × 1013 cm3 mol−1 s−1 was found for the temperature range of the present experiments.
