Constants I Periodic TableThe standard free energy of formation, AG; , of a substance isthe free energy change for the formation of one mole of thesubstance from the component elements in their standardstates. These values are applicable at 25°C and are found inthermodynamic tables.Part ABased on the standard free energies of formation, which of the following reactionsrepresent a feasible way to synthesize the product?The value of AG; for a substance gives a measure of thethermodynamic stability with respect to the componentelements. Negative values for a formation reaction indicatethermodynamic stability of the product. In other words, thecompound formed does not spontaneously decompose backinto the component elements. Positive values for a formationreaction indicate thermodynamic instability of the product.Thus, the compound will spontaneously decompose, thoughthe rate may be slow.Drag the appropriate items to their respective bins.ResetНе2Na(s) + O2(g)→N22O2(s)AG: = -451.0 kJ/mol2C(s) + 2H2(g)¬→C2H4(g)AG; = 68.20 kJ/molThe sign of AG; can be used to predict the feasibility ofsynthesizing a substance from its component elements.
