Calculate the change in entropy for the following phase transitions.

a. One mole of mercury liquid, Hg, freezes at its normal melting point of -38.9째C. The enthalpy of fusion of mercury is 2.33 kJ/mol.

b. One mole of carbon tetrachloride, CCl₄, vaporizes at its normal boiling point of 77.0째C. The enthalpy of vaporization of carbon tetrachloride is 29.89 kJ/mol.
