Question

Calculate the equilibrium concentrations of N2O4 and NO2 after the extra 1.00 mol of NO2 was added to 1.00 L of solution.

the reaction N2O4 = 2NO2 is allowed to reach equilibrium in a chloroform solution at 25 °C. The equilibrium concentrations are 0.449 mol·L–1 N2O4 and 2.24 mol·L–1 NO2 the equilibrium constant, Kc, for this reaction = 11.175
