71 Determine the slope (in atm/K) of a solid- liquid coexistence line (in a P-T phase diagram) at 273.15 K, given that AHfus = 6.01 kJ /mol, Vi 0.0180 L/mol, and Vs 0.0196 L/mol. Make sure your slope has appropriate units for the type of phase diagram we are dealing with (i.e. it should only have pressure and temperature units).
