The Born-Haber cycle is a series of steps that represent the formation of an ionic compound from a metal and a nonmetal. For example, the steps in a Born-Haber cycle for the formation of NaCl(s) consist of sublimation of the metal Na atom (?Hsubl-Na) to form a gaseous Na atom, bond dissociation of the chlorine molecule (BECl2) to form a gaseous Cl atom, ionization energy of the sodium atom (IENa) to form a gaseous Na+ ion, electron affinity of the chlorine atom (EACl) to form a gaseous Cl- ion, and the lattice energy of NaCl (LENaCl) involving the coalescing of the gaseous Na+ and Cl- ions to form a solid NaCl formula unit. With the above summary in mind, which particular steps of the Born-Haber cycle would be represented in the following reaction? K(g) + F(g) ? K+(g) + F-(g) A. IEK and EAF B. BEF2 and EAK C. BEK and BEF D. ?Hsubl-K, IEK and EAF
