The phase diagram for \(\mathrm{SO}_{2}\) is shown here.

(a) What does this diagram tell you about the enthalpy change in the reaction \(\mathrm{SO}_{2}(l) \longrightarrow \mathrm{SO}_{2}(g)\) ?

(b) Calculate the equilibrium constant for this reaction at \(100^{\circ} \mathrm{C}\) and at \(0^{\circ} \mathrm{C}\).

(c) Why is it not possible to calculate an equilibrium constant between the gas and liquid phases in the supercritical region?

(d) At which of the three points marked in red does \(\mathrm{SO}_{2}(g)\) most closely approach ideal-gas behavior?

(e) At which of the three red points does \(\mathrm{SO}_{2}(g)\) behave least ideally?
