The change in energy for which of the following processes corresponds to the electron affinity of bromine? A)Br₂(g)→ 2Br(g) B)Br(g)+ e^-→ Br^-(g) C)Br⁺(g)+ Br^-(g)→ Br₂(l) D)Br(g)→ Br⁺(g)+ e^- E)Br^-(g)→ Br(g)+ e^-

Question

Quizplus · Accepted Answer

The process in option B corresponds to the electron affinity of bromine because it involves adding an electron to a bromine atom in the gas phase to form a negative ion. The change in energy for this process is equal to the electron affinity of bromine. The other processes listed do not involve the addition of an electron to a bromine atom in the gas phase, and therefore do not correspond to the electron affinity of bromine.
