6. (15 points) a. Draw the heating curve for the following for an unknown compound. Label each phase of the diagram with the appropriate state (s) of matter. b. How much energy is removed from a 6.8 g of an unknown sample at 415K to solidify the sample and lower the temperature to 225K. The boiling point of the unknown compound 360K. The melting point is 265K. Assume the molar mass of the unknown compound is 132.4 g/mol. The following values are the specific heat capacities of each phase and the change in enthalpy for each phase change: Gaseous C: 1.35 J/g°C Liquid C: 1.56 J/g°C Solid C: 1.25 J/g°C AHvap 29.45 kJ/mol 1 AHfus 9.55 kJ/mol 7. (5 points) Carbon tetrachloride has a normal boiling point of 67.9°C and a heat of vaporization of 42.7 kJ/mol. What is the vapor pressure of carbon tetrachloride at 12.0°C?
