Free energy of formation table

WebThe JANAF tables (1) present free energy functions referenced to 298.15 K and the Gibbs free energy of formation A/G"(T). According to convention, the free energy of formation of the elements in their pure form, at the temperature of interest, is taken as zero. Thus At.G°(T)is zero for all pure elements. However it is not zero for compounds. http://www.chemistry.alanearhart.org/resources/Handouts/freeenergy-qr.pdf
