The element oxygen was prepared by Joseph Priestley in 1774 by heating mercury(II) oxide:
         HgO(s) → Hg(l) + 1/2O2(g),  ΔH° = 90.84 kJ/mol.
Estimate the temperature at which this reaction will become spontaneous under standard state conditions.
         S°(Hg) = 76.02 J/K·mol
         S°(O2) = 205.0 J/K·mol
         S°(HgO) = 70.29 J/K·mol
◦ 108 K
◦ 430 K
◦ 620 K
◦ 775 K
◦ 840 K
