Temperature dependence of the rate constant for the reaction OH + H 2 S

Absolute rate constants for the reaction of OH with H 2 S have been measured over the temperature range of 239–425 K using the flash photolysis–resonance fluorescence technique. The results showed that the rate constants deviate slightly from Arrhenius behavior but can still be represented adequately by the following Arrhenius equation:\documentclass{article}\pagestyle{empty}\begin{document}$$k_{II} {\rm =}(7.8{\rm} \pm {\rm 2}{\rm .6}){\rm} \times {\rm 10}^{{\rm - 12}} {\rm exp[- (146} \pm {\rm 105)/}T]{\rm cm}^{\rm 3} /{\rm molec} \cdot {\rm s}s$$\end{document} Comparisons with recent literature values are presented.
