The following data was obtained experimentally during the heating of solid A. Use the data to answer the following questions [you may assume that the system is at equilibrium at all times]: 45000 40000 35000 30000 25000 20000 15000 10000 5000 100 200 300 400 500 600 700 800 900 1000 Temperature (°C) (a) What is the melting temperature of this solid? (b) What are the heat-capacities of the solid and liquid phases? (c) Calculate AH,-1,AS-1, AGs-1 at the equilibrium melting point. Enthalpy (J/mole) (d) What is AH,¬1 at 0°C? (e) Calculate AG-s for an undercooling of 100°C below the melting point. The following data was obtained experimentally during the heating of solid A.
