In the Born-Haber cycle for KI(s),which of the following processes corresponds to the electron affinity of I? A)I(g)→ I⁺(g)+ e^- B)KI(s)→ K⁺(g)+ I^-(g) C)I^-(g)→ I(g)+ e^- D)I₂(g)→ 2I(g) E)I(g)+ e^- → I^-(g)

The process that corresponds to the electron affinity of I is the gain of an electron by I. This is expressed in option E, where I gains an electron to become I^-(g). This is the only process in the given options that involves the electron affinity of I.
