Cp is the molar heat capacity at constant pressure….

Cp is the molar heat capacity at constant pressure. The value of Cp is 37.2 J K–1 mol–1 for NO2 and 77.3 J K–1 mol–1 for N2O4. Calculate the equilibrium constant K, G°, H°, and S° for the reaction at 500 K. Formulae can be used without proof and Cp can be assumed to not vary with temperature between 298 K and 500 K.
