Following are data for \(G^{E} \text { and } H^{E}\) (both in \(\mathrm{J} \cdot \mathrm{mol}^{-1}\)) for equimolar mixtures of the same organic liquids. Use all of the data to estimate values of \(G^{E}, H^{E}, \text { and } T S^{E}\) for the equimolar mixture at \(25^{\circ} \mathrm{C}\).

\(∙ \text { At } T=10^{\circ} \mathrm{C}: G^{E}=544.0, H^{E}=932.1\)

\(∙ \text { At } T=30^{\circ} \mathrm{C}: G^{E}=513.2, H^{E}=893.4\)

\(∙ \text { At } T=50^{\circ} \mathrm{C}: G^{E}=494.2, H^{E}=845.9\)

Suggestion: Assume \(C_{P}^{E}\) is constant and use material developed in Example 10.10.
