Csf lattice enthalpy

WebFactors affecting lattice enthalpy. The two key factors which affect lattice energy, ΔH latt ꝋ, are the charge and radius of the ions that make up the crystalline lattice; Ionic radius. The lattice energy becomes less exothermic as the ionic radius of the ions increases; This is because the charge on the ions is more spread out over the ion when the ions are larger WebWhereas lattice energies typically fall in the range of 600–4000 kJ/mol (some even higher), covalent bond dissociation energies are typically between 150–400 kJ/mol for single …
