Regarding the reaction rate constan

Regarding the reaction rate constants, evaluation by the NASA/JPL panel has been conducted from 1977, and the recommended rate constants have been renewed every few years. The most recent evaluation was obtained in Evaluation 17 (Sander et al., 2011). Another evaluation has been reported by the IUPAC Subcommittee on Gas Kinetic Data Evaluation for Atmospheric Chemistry as Vol. I Inorganic Species, Vol. II Organic Species, Vol. III Inorganic Halogen Species, Vol. IV Organic Halogen Species in 2004, 2006, 2007 and 2008, separately (Atkinson et al., 2004, 2006b, 2007, 2008). More recent data was updated on a web page (Wallington et al., 2012). These recommend values are extremely useful for atmospheric chemistry research, and those values are fully quoted in this chapter. In principle, the temperature ranges to be applied for temperature dependent rate constant formulas are taken from the IUPAC subcommittee report, and the values of enthalpy of reactions H are given at 298K calculated from the heat of formation given in Table 2.5 at the end of this book.
