Über die Reaktionen von F‐Atomen mit H2O, H2O2und NH3

The reaction of H2O, H2O2, and NH3with an excess of F‐atoms was investigated in an isothermal flow system. The following rate constants were obtained{article}{empty}{document}$ {array}{*{20}c} {k1({ F} + { H}_2 { O}) = (2.5 ± 0.6) · 10¹³ { exp}({ - {{(400 ± 70){ K}}}{T}} ){{{ cm}^3 }}{{{ mol s}}}243 < T < 369{ K}} \\ {k_3 ({ F} + { H}_2 { O}_2) = (3 ± 1) · 10¹³ {{{ cm}^3 }}{{{ mol s}}}} \\ {k_5 ({ F} + { NH}_3) = (1.5 ± 0.8) · 10¹⁴ { exp}({ - {{(650 ± 150){ K}}}{T}} ){{{ cm}^3 }}{{{ mol s}}}250 < T < 250{ K}.} \\ {array} ${document} A computer simulation of the measured concentration profiles of intermediates and final products allowed the determination of the rate constants of the consecutive reactions.
