Question 1

The enthalpy of fusion of naphthalene, C10H8, is 19.1 kJ/mol at 78.2°C, its melting point. Calculate the entropy of fusion at the melting point.
◦ ΔS°fus = 54.4 J/(K ∙ mol)
◦ ΔS°fus = -1.49 J/(K ∙ mol)
◦ ΔS°fus = 244 J/(K ∙ mol)
◦ ΔS°fus = 1.49 J/(K ∙ mol)

Question 2

Imagine a reaction that results in a change in both volume and temperature, as shown in the diagram below. What is the sign of the work being done and the sign of the enthalpy change involved in this reaction?


◦ w = + and ΔH = +
◦ w = + and ΔH = -
◦ w = - and ΔH = +
◦ w = - and ΔH = -
