Web17 nov. 2012 · There are many variables making this kind of reactions endo or exothermic. As they have as result a gas (and the reactives are liquid or solid), the final entropy of the system is many times higher as the initial entropy. This has no relation with enthalpy variation (negative means endothermic, positive means exothermic). Web26 nov. 2024 · Caesium chloride has a different packing arrangement of ions in its crystal, and that has a small effect on the lattice enthalpy. The effect is small enough that it doesn't actually affect the trend. Calculating lattice enthalpy
