The lattice energy is the most important factor in making the formation of ionic crystals exothermic and spontaneous. ![]() Calculate the net energy change in kJ/mol when solid Al 2O 3 is formed from its elements: 2 Al (s) + 3/2 O 2 (g) → Al 2O 3 (s). Multiply the electron affinity by 2 since there are 2 F atoms.īack to Formation of Ionic Compounds: TheĮxercise 2. Add the equations and the energies to get the net equation and net energy. Sketch a Born-Haber cycle for the process.įirst write the equations and energy for each step. ![]() Calculate the net energy change in kJ/mol when solid MgF 2 is formed from its elements: Mg (s) + F 2 (g) → MgF 2 (s).
