The standard enthalpy of fusion of an inorganic compound is 5.75 kJ/mol. If the temperature at which this phase change occurs is 35.51 °C, determine ΔS°fus (in J/mol/K) for this compound. Report your answer to three significant figures.
One mole of liquid naphthalene at its freezing point of 80 ˚C is brought into contact with a very large ice-water bath, which remains at 0 ˚C as the naphthalene freezes and cools to 0˚C. The enthalpy of fusion of naphthalene is 19.2 kJ mol-1 and ~ C p for solid naphthalene is 180 J K-1 mol-1. Calculate the decrease in entropy for the naphthalene and the increase in entropy for the overall system (naphthalene + ice-water bath).
