The following reaction is exothermic: 3NO(g) N2O(g) NO2(g) Predict and explain the effect of each of the following stresses on the position of equilibrium. (a) N2O(g) is added to the equilibrium mixture without change of volume or temperature. (b) The volume of the equilibrium mixture is reduced at constant temperature. (c) The temperature of the equilibrium mixture is decreased. (d) Gaseous argon (which does not react) is added to the equilibrium mixture while keeping both the total gas pressure and the temperature constant. (e) Gaseous argon is added to the equilibrium mixture without changing the volume.
