Question 1

When heated, mercury(II) oxide decomposes into elemental mercury and oxygen:

2 HgO(s) → 2 Hg(l) + O2(g)ΔH° = 181.6 kJΔS° = 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.
◦ 566°C
◦ -34.8°C
◦ 840°C
◦ 34.8°C

Question 2

Methanol can be produced from carbon monoxide and hydrogen with suitable catalysts:

CO(g) + 2 H2(g) → CH3OH(l) at 25°CΔH° = -128.1 kJ and ΔS° = -332 J/K


Find ΔG° at 25°C.
◦ -157.2 kJ
◦ 157.2 kJ
◦ 98.9 kJ
◦ -29.1 kJ
