The high enthalpy of formation of NCl3, is due to large difference in the size of the N and Cl atoms, as Nitrogen belongs to second period and Cl atoms belongs to third period, this large difference makes the N-Cl bond weak, whereas, in NF3, since the size of the atoms is small, as both the atoms belongs to second period, therefore, the N-F bond is strong and it is an exothermic compound.
