a) Bond enthalpy of a molecule is defined in terms of a gas-phase reaction. This is because in gas-phase, the interactions are negligible. In liquid and solid phase, the molecules have interactions.
b) Fluorine molecule has one F-F bond.
Fluorine molecule dissociates to give two fluorine atoms.
Thus, the enthalpy of formation of fluo...
