✦ Synopsis

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- rameters for the reactions

where X = H or D, relative to CF:j radical recombination are given by log kHlkf'2 = (5.12 f 0.11) -(16,804 f 335)/8 log kDlkf/' = (5.03 f 0.16) -(17,803 f 456)/8 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.

Earlier arguments concerning D(CF302-CF3) and D(CF3-02) are shown to be probably wrong. New values of 86 and 49 kcal/mol, respectively, are derived. C-0 bond strengths are compared between CF3-and CH3-containing compounds. This relation is of value only if D,(Oz) is independent of X. This is equival
