Given the following information: Energy of sublimation of Li(s) = 166 kJ/mol Bond energy of HCl = 427 kJ/mol Ionization energy of Li(g) = 520. kJ/mol Electron affinity of Cl(g) = 349 kJ/mol Lattice energy of LiCl(s) = 829 kJ/mol Bond energy of H2 = 432 kJ/mol Calculate the net change in energy for the following reaction: 2Li(s)+2HCl(g)2LiCl(s)+H2(g). The lattice energy is usually the most important energy factor in determining the stability of an ionic compound. of ionic materialsthat is, their resistance to scratching or abrasionis also related to their lattice energies. Explain. Q:Which substance do you expect to have the greatest lattice energy: MgF2, CaF2, or ZrO2? the lattice energy for MgF 2 should be more negative than the lattice energy for NaF.
