Investig ation of K inetic isotope effects on reaction of me thane with radical of thrifluo romethane

In this investigation, reaction of methane with radical of thrifluoromethane has b een studied. This reaction is a hydrogen a bstraction reaction and produce tw o kind of products. We study these two c hannels and determine the kinetic i sotope effect in these re actions.(...)In ۱۹۶۷ G iles, R.D.; Quick, L.M. and Whittle , E. investig ated reaction R۴ by Ga s chromatography technique and reported it’s rate expression equal to ۱.۳۴±۱.۳x۱۰-۱ e۷.۱۱ [±۰.۴۳ kJ/mole]/RT (cm۳ molecule-۱ s-۱), at ۴۱۷ - ۶۲۵ K [۱]. I n ۱۹۶۴ Car michael, H. and Johnston, H.S. used IR absorpt ion technique and reported rate constant of reaction R۴ ۱.۵۸x۱۰-۱۲ [cm۳/molecule s] e-۴۶.۰۶ [±۰.۴۶ kJ/mole]/ RT at ۳۵۷ - ۵ ۳۴ K [۲].
