The reaction of CF3 radicals with Ha0 (D20) has been studied over the range of 533-723 K using the photolysis and the pyrolysis of CFJ as the free radical source. Arrhenius pa- where klkE/* is in ~r n~'~/ r n o l~'~-s~~~ and B = 2.303RT/cal/mol. The activation energy and the primary kinetic isotope effect have been compared with those derived from the BEBO method.
The reaction of CzFs radicals with HCN has been studied over the range of 533473 K using the pyrolysis of pentafluoroethyl iodide as the free-radical source. Arrhenius parameters for the reaction hH C2F:, + HCN -+ C2FsH + CN relative to C4F10 recombination are given by log kH/kc"2 = (5.36 i 0.15) -(57.3 z t l.8)/0 where 0 = 2.303RT kJ/mol and kH/k,'/2 is in cm"/2/mo11/2 . s1l2.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
