Web selected atct [1, 2] enthalpy of formation based on version 1.118 of the thermochemical network this version of atct results was partially described in ruscic et al. For example, although oxygen can exist as ozone (o 3 ), atomic. Web in standard tables, n x 2 at stp has an enthalpy formation ( δ h f) listed as 0 k j / m o l, entropy ( s) as 0.1915 k j / k, and free energy of formation ( δ g f) as 0 k j / m o l. Web the standard enthalpy of formation of any element in its standard state is zero by definition. The list is limited to 20 most important contributors or, if less, a number. Web the standard enthalpy of formation is defined as the enthalpy change when one mole of a substance in the standard state (1 atm of pressure and 298.15 k) is. M [kg/kmol] hfo [kj/kmol] carbon.
