the standard reaction free energy of the following chemical reaction: P4 (s) +20HF (g) → 4PF5 (g) + 10H₂ (g)

Constants I Periodic Table The standard free energy of formation, AG; , of a substance is the free energy change for the formation of one mole of the substance from the component elements in their standard states. These values are applicable at 25°C and are found in thermodynamic tables. Part A Based on the standard free energies of formation, which of the following reactions represent a feasible way to synthesize the product? The value of AG; for a substance gives a measure of the thermodynamic stability with respect to the component elements. Negative values for a formation reaction indicate thermodynamic stability of the product. In other words, the compound formed does not spontaneously decompose back into the component elements. Positive values for a formation reaction indicate thermodynamic instability of the product. Thus, the compound will spontaneously decompose, though the rate may be slow. Drag the appropriate items to their respective bins. Reset Не 2Na(s) + O2(g)→N22O2(s)…

A student determines the value of the equilibrium constant to be 7.49×10-37 for the following reaction. H,S(g) + 2H2O(1)3H2(g) + SO2(g) Based on this value of Kegi AG° for this reaction is expected to be (greater, less) than zero. Calculate the free energy change for the reaction of 2.03 moles of H,S(g) at standard conditions at 298K. AG. rxn kJ
