Question
In the equilibrium N₂(g) + O₂(g) <=> 2NO(g) , adding an inert gas at constant pressure will shift the equilibrium in which direction?
Explanation
Adding an inert gas at constant pressure decreases the partial pressures of reactants and products. Since Δ n = 0 (2 mol reactants = 2 mol products), there is no shift.
