Kinetic study of reaction of methane with radical of thrifluoromethane

In this investigation, reaction of methane with radical of thrifluoromethane has been studied. This reaction is a hydrogen abstraction reaction and produce two kind of products. We study these twochannels and determine the kinetic isotope effect in these reactions. CH4+CF3 →CH3CF3+H (R1)In 1967 Giles, R.D.; Quick, L.M. and Whittle, E. investigated reaction R1 by Gas chromatography technique and reported it’s rate expression equal to 1.34±1.3x10-1 e7.11 [±0.43 kJ/mole]/RT (cm3 molecule-1 s-1), at 417 - 625 K [1]. In 1964 Carmichael, H. and Johnston, H.S. used IR absorption technique and reported rate constant of reaction R4 1.58x10-12 [cm3/molecule s] e-46.06 [±0.46 kJ/mole]/RT at 357 - 534 K [2].
