Question
The 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) ped with a piston, is allowed to reach equilibrium. Subsequently, the piston is pushed inward. As a result, the equilibrium will: Shift to the rightExplanation / Answer
8) According to Le chatliers principle When any system at equilibrium is subjected to change in concentration, temperature, volume, or pressure, then the system readjusts itself to (partially) counteract the effect of the applied change and a new equilibrium is established.
However when an inert gas is added there is no shift in equilibrium. An inert gas (or noble gas), Argon in this case, that does not react with other elements or compounds. Adding an inert gas into a gas-phase equilibrium at constant volume does not result in a shift. This is because the addition of a non-reactive gas does not change the equilibrium equation, as the inert gas appears on both sides of the chemical reaction equation. While it is true that the total pressure of the system increases, the total pressure does not have any effect on the equilibrium constant; rather, it is a change in partial pressures that will cause a shift in the equilibrium.
