As O_2 (I) is cooled at 1 atm pressure , it freezes to form solid I at 54.5 K. At a lower temperature , solid rearrange to solid II,which has a different crystal that for the phase transition solid to slid II , DeltaH=-743.1 Jmol^(-1) and DeltaS=-17.0JK^(-1) mol^(-1) . At what temperature are solids I and II in equilibrium ? |
