Problem

An aqueous solution at equilibrium contains the reaction N2O4(aq)⇌2 NO2(aq)N_2O_4(aq) \rightleftharpoons 2\,NO_2(aq). One hundred milliliters of distilled water are added to the original 50 mL equilibrium mixture. Predict the direction in which the equilibrium position will shift after mixing, and briefly justify your answer in terms of the dissolved particles on each side of the equation.
