The molar entropies of \( \mathrm{HI}(\mathrm{g}) \) and \( \mathrm{I}(\mathrm{g}) \) at 298 K are 206.5 114.6 , and \( 180.7 \mathrm{~J} \mathrm{~mol}^{-1} \mathrm{~K}^{-1} \) respectively. Using the \( \Delta \mathrm{G}^{\circ} \) given below, calculate the bond energy of HI . \( \mathrm{HI}(\mathrm{g}) \longrightarrow \mathrm{H}(\mathrm{g})+\mathrm{I}(\mathrm{g}) ; \Delta \mathrm{G}^{\circ}=271.8 \mathrm{~kJ} \) \( \begin{array}{ll}\text { (a) } 282.4 \mathrm{~kJ} \mathrm{~mol}^{-1} & \text { (b) } 298.3 \mathrm{~kJ} \mathrm{~mol}^{-1} \\ \text { (c) } 290.1 \mathrm{~kJ} \mathrm{~mol}^{-1} & \text { (d) } 315.4 \mathrm{~kJ} \mathrm{~mol}^{-1}\end{array} \)
