Calculate the equilibrium compositions due to the decompositionof 1 mole of nitrogen tetroxide at 25C and 1 bar in each of thefollowing cases.

N2O4(g) <==> 2NO2(g)Â Â Â

N2O4Â Â : Î”Hf (formation) = 9160 joules/mole and Î”Gf(formation) = 97540 joules/mole at 298 K
NO2 :Â Â Î”Hf (formation) = 33180 joules/mole and Î”Gf(formation) = 51310 joules/mole at 298 K of

a.) Use the reaction equilibrium method with extent of reaction Î¾,and let the initial state be pure N2O4.

b.) Use the reaction equilibrium method with extent of reaction Î¾,and let the initial state be 1 mole inert Argon in addition to 1mole of N2O4.
