Adding an inert gas at constant volume to an equilibrium system will:

A.Have no effect on the equilibrium position

B.Shift the equilibrium toward the side with fewer moles of gas

C.Shift the equilibrium toward the side with more moles of gas

D.Decrease the equilibrium constant

Explanation

Core Concept

Adding an inert gas at constant volume increases the total pressure but does not change the partial pressures of the reacting gases. Since the partial pressures remain the same, Qc is unchanged and no shift occurs.

Correct Answer

AHave no effect on the equilibrium position
