Lattice Energy: The Born-Haber cycle - Chemistry LibreTexts

WebJul 16, 2024 · The lattice energy of a compound is a measure of the strength of this attraction. The lattice energy ( ΔHlattice) of an ionic compound is defined as the energy required to separate one mole of the solid into its component gaseous ions. For the ionic solid MX, the lattice energy is the enthalpy change of the process: WebOct 4, 2024 · Lattice enthalpy is a measure of the strength of the forces between the ions in an ionic solid. The greater the lattice enthalpy, the stronger the forces. Those forces are only completely broken when the ions are present as gaseous ions, scattered so far apart that there is negligible attraction between them.
