Consider the reaction described by the following chemical equation. 2Ag2S (s) + 2H2O (l) ⟶4Ag (s) + 2H2S (g) + O2 (g) ΔH∘rxn=595.5kJmol The change in enthalpy for this reaction can be determined theoretically by using the standard enthalpies of formation for the species involved. ΔH∘rxn=∑nΔH∘fproducts-∑nΔH∘freactants What is the value for the standard enthalpy of formation for Ag (s) that would be used in the equation above?
