As O2(l) is cooled at 1 atm, it freezes at 54.5 K to form solid I. At a lower temperature, solid I rearranges to solid II, which has a different crystal structure. Thermal measurements show that H for the I II phase transition is 743.1 J/mol, and S for the same transition is 17.0 J/K mol. At what temperature are solids 1 and II in equilibrium?
