WebIn these cases the polarization energy E pol associated with ions on polar lattice sites may be included in the Born–Haber cycle. As an example, one may consider the case of iron-pyrite FeS 2 . It has been shown that neglect of polarization led to a 15% difference between theory and experiment in the case of FeS 2 , whereas including it ... WebBorn Haber Cycles. A Born Haber cycle (also known as a Born-Haber cycle, which is what we'll call it from now on) is a theoretical model we use to calculate lattice enthalpy. We do this by comparing enthalpy changes involved in forming an ionic lattice from its gaseous ions to the standard enthalpy of formation of the ionic compound.
