Solid HgO,liquid Hg,and Gaseous O₂ Are Placed in a Glass

Solid HgO,liquid Hg,and gaseous O₂ are placed in a glass bulb and allowed to reach equilibrium.
2HgO(s)
2Hg(l) + O₂(g) ; ΔH = 181.6 kJ
The amount of Hg(l) in the bulb could be increased

A) by removing some HgO(s) .
B) by adding an inert gas.
C) by adding some HgO(s) .
D) by increasing the pressure.
E) by increasing the temperature.
