To construct the energy cycle diagram (Born-Haber cycle) for the formation of solid aluminium fluoride (AlF3\text{AlF}_3), we need to consider the following steps and their enthalpy changes:

Given Data:

  • Standard enthalpy of formation of AlF3(s)\text{AlF}_3\text{(s)}: ΔHf∘(AlF3)=−1301 kJ mol−1\Delta H_f^\circ(\text{AlF}_3) = -1301 \text{ kJ mol}^{-1}
  • Enthalpy of atomization of aluminium: ΔHatom∘(Al)=+314 kJ mol−1\Delta H_{atom}^\circ(\text{Al}) = +314 \text{ kJ mol}^{-1}
  • Bond dissociation energy of fluorine: D(F-F)=+158 kJ mol−1D(\text{F-F}) = +158 \text{ kJ mol}^{-1}
