lattice enthalpy (lattice energy) - chemguide

WebThe other definition says that lattice energy is the reverse process, meaning it is the energy released when gaseous ions bind to form an ionic solid. As implied in the definition, this process will always be exothermic, and thus the value for lattice energy will be negative. Its values are usually expressed with the units kJ/mol. WebThanks that covers a lot. I suppose if the surrounding temperature were significantly high then heat will still be emitted(so still just as exothermic), but if it were super high then after the heat is emitted it'd get reabsorbed, and it's just boil and then you'd have an endothermic state of matter transition taking place at the same time as the exothermic chemical … WebCollege Board cmake print to screen
