Question

The sublimation energy of `I_(2)(s)` is 57.3 kJ `//` mol and the enthalpy of fusion is 15.5 kJ `//` mol. The enthalpy of vaporisation of `I_(2)` is
A. 41.8 kJ `//` mol
B. `-41.8 kJ //` mol
C. 72.8 kJ`//` mol
D. `-72.8 kJ // `mol

Answer 1

Correct Answer - a
`DeltaH_("sub")= DeltaH_("fusion") + DeltaH _(vap)`
