Using thermodynamic data given for NO2 and N2O4, determine the fraction of N2O4 that will dissociate into two NO2 molecules if one mole of pure N2O4 is introduced to a 10 liter constant volume, constant temperature of 298K reactor. In addition determine the initial and final pressures within the reactor and the composition of the equilibrium vapor.
