In the Born-Haber cycle for the formation of , which of the following terms represents an exothermic — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Sublimation, ionization, and bond dissociation all require energy input (endothermic). The addition of an electron to chlorine (electron affinity) and the formation of the solid lattice from gaseous ions (lattice energy) release energy (exothermic).
