If the sublimation energy and enthalpy of fusion of \( \mathrm{I}_{2} \) are \( 57.3 \mathrm{~kJ} \mathrm{~mol}^{-1} \) and \( 15.5 \mathrm{~kJ} \mathrm{~mol}^{-1} \), respectively then, the enthalpy of vaporisation of \( \mathrm{I}_{2} \) will be
(a) \( -72.8 \mathrm{~kJ} \mathrm{~mol}^{-1} \)
(b) \( 72.8 \mathrm{~kJ} \mathrm{~mol}^{-1} \)
(c) \( -41.8 \mathrm{~kJ} \mathrm{~mol}^{-1} \)
(d) \( +41.8 \mathrm{~kJ} \mathrm{~mol}^{-1} \)
