Description:
The relevant thermochemistry of sulfur oxides is discussed, and selected 'best' thermochemical values for use in kinetic systems are presented. Although the kinetics of air pollution and combustion involve mostly homogeneous gas phase reactions, the data taken from condensed phases were also considered. This was accomplished by using empirical rules that were used to translate condensed phase values to equivalent gas phase values. All available research through 1976 on the thermochemistry of organic and relevant inorganic sulfur containing molecules and radicals is reviewed. Some significant or controversial kinetic steps important in air pollution chemistry and combustion are examined. The thermochemistry of divalent, tetravalent, and hexavalent sulfur compounds, the relevant bond strengths of radicals, and the kinetics of oxidation processes are discussed. The entropy and heat of formation measured experimentally or estimated are presented for selected sulfur molecules and radicals.
