SO2
SO2 provides ideal gas thermodynamic properties for sulfur dioxide gas valid over the temperature range from 200 K to 6000 K based on the property information provided in McBride et al. (2002). The reference state for specific enthalpy is based on the enthalpy of formation relative to the elements at 25 C. The reference state for specific entropy is based on the Third Law of Thermodynamics. The reference values are from:

The viscosity correlation is valid for temperatures between 200 K and 1250 K. The thermal conductivity correlation is applicable for temperatures between 250K and 900 K.
