THERMODYNAMIC DATA AT 298 K The GRI-Mech thermochemistry is based upon standard databases, including the NASA-Lewis and Technion archives. This was supplemented by a critical review of the standard enthalpies of formation for radical species. Clicking on the species symbols in the following summary table will bring up a full table of the molar heat capacity, entropy and standard enthalpy of ...
