Nitrogen dioxide (ΔH°f = 33.2 kJ/mol, S° = 240.1 J/mol K) can be prepared by the combustion of nitrogen (S° = 191.6 J/mol K) with oxygen (S° = 205.2 J/mol K). Calculate the equilibrium constants (Kp and Kc) for the formation of NO2 at 500 K. Use the assumption that ΔHº and ΔSº does not vary with temperature.
