The rate coefficient, k, of the reaction \documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm H}_2 {\rm O} + {\rm CN} \to {\rm HCN} + {\rm OH} $$\end{document} has been determined in the temperature range 2460-2840 K using a shock tube technique. C2N2—H2O—Ar mixtures were heated behind incident shock waves and the CN and OH concentration time histories were monitored simultaneously using broad-band absorption near 388 nm (CN) and narrow-line laser absorption at 306.67 nm (OH). The rate coefficient expression providing the best fit to the data was \documentclass{article}\pagestyle{empty}\begin{document}$$ k = 2.3{\rm} \times {\rm 10}^{{\rm 13}} \exp (- 6700/T){\rm cm}^3 /{\rm mol s} $$\end{document} with uncertainty limits of about ±45% in the temperature range 2460-2840 K. The rate coefficient of the reverse reaction was calculated using detailed balancing, and its extrapolation to lower temperatures was compared with previously published results.
