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
N2O4  : ΔHf (formation) = 9160 joules/mole and ΔGf(formation) = 97540 joules/mole at 298 K
NO2 :  ΔHf (formation) = 33180 joules/mole and ΔGf(formation) = 51310 joules/mole at 298 K of
a.) Use the reaction equilibrium method with extent of reaction ξ,and let the initial state be pure N2O4.
b.) Use the reaction equilibrium method with extent of reaction ξ,and let the initial state be 1 mole inert Argon in addition to 1mole of N2O4.
