An example of auto-catalytic reaction
Oxidation of oxalic acid by acidified KMnO4
Thermal decomposition of KClO3 in presence of MnO2
Hydrogenation of oils in presence of nickel
Decomposition of Hydrogen Peroxide in presence of Ferric chloride
Mn2+ formed in the oxidation of oxalic acid by acidified KMnO4 acts as auto catalyst
