# Comproportionation reactions

Is the following reaction a comproportionation reaction?

$$\ce{NH4NO3 -> N2O + H2O}$$

The wikipedia definition says:

Comproportionation or synproportionation is a chemical reaction where two reactants, each containing the same element but with a different oxidation number, form a product in which the elements involved reach the same oxidation number.

In the reaction,only one reactant is involved( the definition says two) but two elements with different oxidation number react to form element in an intermediate oxidation state, so what can we say about it?

• You do have two reactants, $\ce{NH4+}$ and $\ce{NO3-}$. This reaction is very similar to one of the examples given on the Wikipedia page. – Tyberius Apr 30 at 17:23
