By allowing the t ‐butoxy radical to decompose in the presence of nitric oxide, it has been possible to determine rate constants for decomposition by the measurements of the relative rates (2) and (3)Process (3) is clearly pressure dependent. The value of k 3 (∞) has been determined in the presence of several inert gases (CF 4 , SF 6 , N 2 , and Ar) and a value of k 3 interpolated for atmospheric conditions. The results may be compared with those for other relevant alkoxy radicals at room temperature. Extrapolated values for k 3 in the presence of CF 4 lead to the result\documentclass{article}\pagestyle{empty}\begin{document}$$ k_3 (\infty)/s^{ - 1} = 10^{14.6 \pm 0.6} \exp (- 8052 \pm 604/T) $$\end{document}
