For 10 points, name this class of chemical reactions, exemplified by the rusting of iron, which is characterized by a change in oxidation number.
Disproportionation happens in this class of reactions when different atoms of the same element act as both electron donors and acceptors. The electric potential of reactions of this type can be calculated using the Nernst Equation. Because the net charge remains constant during reactions of this type, they can be analyzed by writing two half-reactions, which occur in the two halves of an electrochemical cell.
