Consider the decomposition of yellow mercury (II) oxide. HgO (s,yellow) ⟶ Hg(l) + 1/2 O2(g) Calculate the standard free energy change at room temperature, ΔG°, using (a) standard free energies of formation and (b) standard enthalpies of formation and standard entropies. Do the results indicate the reaction to be spontaneous or nonspontaneous under standard conditions?
