Standard free energy of formation table
WebbThis table is based on the conventions that ΔGo =ΔHo =0 for the species H+, adenosine, NAD−, and NADP3− at zero ionic strength. Data are obtained from R. A. Alberty, Arch. Biochem. Biophys. 353, 116 (1998). WebbThe free energies of formation of the lowest oxides of most metals are comparatively high, so that an oxide film is formed when these metals are exposed to oxygen, except for very low pressures or very high temperatures. The solubility data usually required is therefore the concentration of dissolved oxygen in equilibrium with the oxide phase.
