According to the balance of N2O4 = 2NO2 at 25 C, the formation enthalpies of N2O4 and NO2 are 3.04 kcal / mol and 8.03 kcal / mol, respectively. Their heat capacity is 9.0 cal / mol.K and 11.4 cal /...

According to the balance of N2O4 = 2NO2 at 25 C, the formation enthalpies of N2O4 and NO2 are 3.04 kcal / mol and 8.03 kcal / mol, respectively. Their heat capacity is 9.0 cal / mol.K and 11.4 cal / mol.K. If K = 1,563 atm at 60 C and 1 atm pressure, what is the equilibrium constant and decomposition degree at 100 C?
