What is the effect of adding an inert gas to a system at equilibrium?

A. Shifts the equilibrium to the left
B. Shifts the equilibrium to the right
C. No effect on the position of equilibrium
D. Increases the number of products

Answer: No effect on the position of equilibrium


Additional Information: Adding an inert gas at constant volume does not affect the position of equilibrium because it does not change the concentrations of reactants or products.
