How to know what species what will disproportionate in a frost diagram?
Accepted Answer
A species will disproportionate in a Frost diagram if the potential for its reduction is lower than the potential for its oxidation. In other words, the species is thermodynamically unstable and will spontaneously decompose to form a lower and higher oxidation state. This can be identified by looking for a species that lies above the line connecting the potential for its reduction and oxidation products on the Frost diagram.
