Question

The element oxygen was prepared by Joseph Priestley in1774 by heating mercury(ll) oxide. HgO(s) ---> Hg(l) +1/2O2(g)    Ho = 90.84 kJ Use the data given below to estimate the temperature at whichthis reaction will become spontaneous under standard stateconditions. So(Hg) = 76.02 J/K .mol So(O2) = 205.0 J/K. mol So(HgO) = 70.29 J/K .mol                               The element oxygen was prepared by Joseph Priestley in1774 by heating mercury(ll) oxide.
