Using the thermochemical data given for NO2 and N2O4 in class, 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 (298 K) reactor. In addition, determine the initial and final pressures within the reactor, and the composition of the equilibrium vapor. Then repeat this calculation at 270 K, both by integrating the constant pressure heat capacities of NO2 and N2O4 to get the accurate value of deltaG_rxn at this temperature, and then again using an equilibrium constant from the van't Hoff equation. Which approach is more accurate, and why?
