Solution: Write an equation corresponding to the electron affinity of Fe3+.

Problem

Write an equation corresponding to the electron affinity of Fe3+.

Solution

Electron affinity is the energy change from the addition of 1 e to 1 mol of gaseous atoms or ions. This is the opposite of ionization energy.

Atom(g) + e → ion(g)         ΔE = –EA
