Autocatalysis of reaction b/w oxalic acid & acidified KMnO4 with Mechanism

Permanganate in acidic solution can oxidize oxalate ions (or oxalic acid). The reaction produces Mn2+, which auto-catalyses this very reaction

Autocatalysis of reaction b/w oxalic acid by acidified KMnO4 with Mechanism

When potassium permanganate undergoes a reaction with acidified oxalate solution,the rate of the reaction is initially slow.It slowly increases in rate due to the formation of Mn2+ ions:

The Mn2+ acts as a homogeneous catalyst because it is easily oxidised to Mn3+ by the MnO4- ions and then reduced back to Mn2+ ions by the C2O42- ions.
