(a) Show that in a binary solution if the solute obeys Henry's law, the solvent obeys the Lewis-Randall rule.

(b) Estimate the fugacity of liquid acetone at \(110^{\circ} \mathrm{C}\) and \(275 \mathrm{bar}\). At \(110^{\circ} \mathrm{C}\) the vapour pressure of acetone is \(4.360 \mathrm{bar}\) and the molar volume of saturated liquid acetone is \(73 \mathrm{~cm}^{3} / \mathrm{mol}\).

(c) The following experimental data are available for \(\mathrm{CO}_{2}\) gas at \(92^{\circ} \mathrm{C}\) :

Find the fugacity of \(\mathrm{CO}_{2}\) at \(100 \mathrm{~atm}\).
Data: For \(\mathrm{CO}_{2}\)
\[ \begin{aligned} T_{c} & =304.1 \mathrm{~K} \\ P_{c} & =72.9 \mathrm{~atm} \end{aligned} \]
