A Sample of Solid Naphthalene Is Introduced into an Evacuated $\circ$

A sample of solid naphthalene is introduced into an evacuated flask. Use the data below to calculate the equilibrium vapor pressure of naphthalene (C₁₀H₈) in the flask at 35 ^$\circ$ C. $\begin{array}{lcc}&\Delta \mathrm{H}^{\circ}{ }_{\mathrm{f}}\left(25^{\circ} \mathrm{C}\right) & \Delta \mathrm{G}^{\circ}_\mathrm{f}\left(25^{\circ} \mathrm{C}\right) \\\hline\mathrm{C}_{10} \mathrm{H}_{8}(\mathrm{s}) & 78.5 \mathrm{~kJ} / \mathrm{mol} & 201.6 \mathrm{~kJ} / \mathrm{mol} \\\mathrm{C}_{10} \mathrm{H}_{8}(\mathrm{g}) & 150.6 \mathrm{~kJ} / \mathrm{mol} & 224.1 \mathrm{~kJ} / \mathrm{mol}\end{array}$

A) 890. mmHg
B) 0.21 mmHg
C) 696 mmHg
