Born-Haber Cycle

See Hess Cycle.

The Born-Haber Cycle is used for calculating Lattice Energy or Enthalpy Change of Formation.

Note

$\Delta H_1+\Delta H_{latt}=\Delta H_f$

$\Delta H_1$ is the sum of enthalpies when you convert the elements in their standard states into gaseous ions, ready to be converted into the ionic compound.
