The element oxygen was prepared by Joseph Priestley in 1774 by heating mercury oxide: HgO(s)->Hg(l) + (1/2)O2(g)

delta H = 90.84 KiloJoule/mol
S(Hg)=76.02 J/K x mol
S(o2)=205.0 J/K x mol
s(HgO) =70.29 J/k x mol

Estimate the temperature at which this reaction will become spontaneous under standard state conditions.
