Post by: Whelan on May 6, 2015
When heated, mercury(II) oxide decomposes into elemental mercury and oxygen:

   2 HgO(s) → 2 Hg(l) + O2(g)   ΔH° = 181.6 kJ   ΔS° = 216.4 J/K

Estimate the temperature at which HgO should begin to decompose if the partial pressure of O2(g) is constant at 1.00 atm.
A) -34.8°C
B) 34.8°C
C) 566°C
D) 840°C
