Problem 79 Consider the reaction:$$\mathrm{H}_{2}(g)+\mathrm{I}_{2}(g) \rightleftharpoons 2 \mathrm{HI}(g)$$The following data show the equilibrium constant for this reaction measured at several different temperatures. Use the data to find \Delta H_{\text { rxn }}^{\circ} and \Delta S_{\text { ren }}^{\circ} for the reaction.$$\begin{array}{|c|c|}\hline Temperature & {K_{\mathrm{p}}} \\ \hline 150 \mathrm{K} & {1.4 \times 10^{-4}} \\ \hline 175 \mathrm{K} & {4.6 \times 10^{-4}} \\ \hline 200 \mathrm{K} & {3.6 \times 10^{-2}} \\ \hline 225\mathrm{K} & {11} \\ \hline 250\mathrm{K} & {15.5} \\ \hline\end{array}

$\Delta H^{\circ}=50.7 \mathrm{kJ} / \mathrm{mol}$ and $\Delta S^{\circ}=226 \mathrm{J} / \mathrm{mol} \cdot \mathrm{K}$
