Given the information below, determine the pressure (in atm) at which an unknown substance will melt at -83.1C. Viquid = 18.3 cm3 mol 1 V solid = 17.1 cm3 mol 1 AHfus = 2.81 kJ mol 1 Use the fact that the temperature and pressure at the triple point of the substance is -114.96C and 0.223 atm. Assume the molar enthalpy and molar volumes are constant as a function of temperature.
