Auto catalyst is a chemical reaction in which, if one of reaction products is also act as a catalyst for the same or coupled reaction. In the given reaction (s).

5 C_{2} O_{4}^{2 -} + 2 M n O_{4}^{-} + 16 H^{+} \to 10 C O_{2} + 2 M n^{2 +} + 8 H_{2} O

is an example of all to catalyst where,

M n^{2 +}

ions act as an auto catalyst.
