Pyrolysis of tetrafluorohydrazine

The pyrolysis of tetrafluorohydrazine has been studied from 578 to 791°K. The stoichiometry has been established as\documentclass{article}\pagestyle{empty}\begin{document}$$ 6{\rm NF}_{\rm 2} \to 4{\rm NF}_{\rm 3} + {\rm N}_{\rm 2} $$\end{document}Reaction rates have been measured and the effects of surface area, inert gas pressure, and nitric oxide have been examined. The rate‐determining step proposed is\documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm 2NF}_{\rm 2} \to {\rm NF}_{\rm 3} + {\rm NF} $$\end{document}and the general rate expression obtained for this is\documentclass{article}\pagestyle{empty}\begin{document}$$ k_1 = 10^{9.0 \pm 0.4} \exp {{ - 36,950 \pm 500} \mathord{\left/ {\vphantom {{ - 36,950 \pm 500} {RTM^{ - 1} \cdot \sec ^{ - 1} }}} \right. \kern-\nulldelimiterspace} {RTM^{ - 1} \cdot \sec ^{ - 1} }} $$\end{document}
