The boiling point elevation constant for toluene is \( 3.32 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1} \). The normal boiling point of toluene is \( 110.7^{\circ} \mathrm{C} \). The enthalpy of vaporisation of toluene would be nearly:
(a) \( 17.0 \mathrm{~kJ} \mathrm{~mol}^{-1} \)
(b) \( 34.0 \mathrm{~kJ} \mathrm{~mol}^{-1} \)
(c) \( 51.0 \mathrm{~kJ} \mathrm{~mol}^{-1} \)
(d) \( 68.0 \mathrm{~kJ} \mathrm{~mol}^{-1} \)
