Question

As a result, the equilibrium will. Shift to the right Shift to the left Not shift at jII d Cannot tell he reaction Ni(s) + 4 CO(g) Ni(CO)_4(g). which takes place in a rigid. closed vessel, is allowed to reach equilibrium. Subsequently, some argon gas (Ar(g)) is added to the vessel without changing its dimensions. As a result, the equilibrium will: Shift to the right Shift to the left Not shift at all Cannot tell The reaction CO(g) + Cl_2(g) COCl_2(g) which takes place in a cylinder equipped with a piston, is allowed to reach equilibrium. Subsequently, the piston is pushed inward. As a result, the equilibrium will: Shift to the right Shift to the left Not shift at all d Cannot tell

Explanation / Answer

Use Le Chatelier's principle:

When any system at equilibrium is subjected to change in concentration, temperature, volume, or pressure, then the system re-adjusts itself to counteract the effect of the applied change and a new equilibrium is established.

6) b

7) b

8) c (no effect on equilibrium on addition of inert gas as volume is constant)

9) a (as volume is decreasing, the reaction proceeds towards less gaseous product)
