Question

Quizplus · Accepted Answer

The Born-Haber cycle relates the formation enthalpy of an ionic compound to the enthalpies of atomization, ionization, electron affinity, and lattice energy. The correct expression includes the sum of the enthalpies of formation of gaseous atoms, ionization energy, and electron affinity, minus the lattice energy.
