The value of \( \Delta H^{\circ} \) for the reaction \( \mathrm{Cu}^{+}(g)+\mathrm{I}^{-}(g) \longrightarrow \mathrm{CuI}(g) \) is \( -446 \mathrm{~kJ} \mathrm{~mol}^{-1} \). If the ionisation energy of \( \mathrm{Cu}(\mathrm{g}) \) is \( 745 \mathrm{~kJ} \mathrm{~mol}^{-1} \) and the electron affinity of \( \mathrm{I}(\mathrm{g}) \) is \( -295 \mathrm{~kJ} \mathrm{~mol}^{-1} \), then the value of \( \Delta H^{\circ} \) for the formation of one mole of \( \mathrm{CuI}(\mathrm{g}) \) from \( \mathrm{Cu}(g) \) and \( \mathrm{I}(\mathrm{g}) \) is:
(A) \( -446 \mathrm{~kJ} \mathrm{~mol}^{-1} \)
(B) \( 450 \mathrm{~kJ} \mathrm{~mol}^{-1} \)
(C) \( 594 \mathrm{~kJ} \mathrm{~mol}^{-1} \)
(D) \( 4 \mathrm{~kJ} \mathrm{~mol}^{-1} \)
