How does the addition of an inert gas at constant volume affect equilibrium?

A. Shifts equilibrium to the left
B. Shifts equilibrium to the right
C. No effect on equilibrium
D. Increases reaction rate

Answer: No effect on equilibrium

Additional Information: Adding an inert gas does not change the partial pressures of the reactants or products, so equilibrium remains unchanged.
