The element oxygen was prepared by Joseph Priestley in 1774 by heating mercury(II) oxide.
HgO(s) Hg(l) + ½O2(g) Ho = 90.84 kJ
Use the data given below to estimate the temperature at which this reaction will become spontaneous under standard state conditions.
So(Hg) = 76.02 J/K mol
So(O2) = 205.0 J/K mol
So(HgO) = 70.29 J/K mol
