Carbon dioxide and argon, which is a noble or inert gas, are placed in a vessel and heated. Equilibrium is reached at some particular temperature. Carbon dioxide dissociates by the following reaction.
2CO₂(g) 2CO(g) + O₂(g)
What is the result of increasing the pressure by adding more argon?
I. The equilibrium shifts to produce more carbon dioxide and reduce the pressure.
II. The equilibrium shifts to remove carbon dioxide and reduce the pressure.
III. The equilibrium does not change because argon is not involved in the reaction.
IV. The equilibrium does not change because the concentrations are not affected.
