Comments:   Rate constant was derived relative to reaction rate of Cl with CF3CF2H and CHClF2. The authors used k(Cl + CF3CF2H) = 2.5 x 10-16 cm3 molecule-1 s-1 [Sehested, J.; Ellermann, T.; Nielsen, O. J.; Wallington, T. J.; Hurley, M. D. Int. J. Chem. Kinet. 1993, 25, 701.] and k(Cl + CF3CF2H) = 1.70 x 10-15 cm3 molecule-1 s-1 [Sander, S. P.; Friedl, R. R.; Golden, D. M.; Kurylo, M. J.; Huie, R. E.; Orkin, V. L.; Moortgat, G. K.; Ravishankara, A. R.; Kolb, C. E.; Molina, M. J.; Finlayson-Pitts, B. J. JPL Publication No. 02-25; NASA Jet Propulsion Laboratory, Pasadena, CA, 2003.] to derive the absolute rate constant. Reported value is the average of the two.
