What happens when you mix potassium permanganate and oxalic acid?

this is an autocatalytic reaction where Mn+2 catalyses the reaction.
the start of the reaction is relatively slow due to absence of catalyst.so usually the oxalic acid solutions is warmed to about 65-79 c before a titration with
KMnO4 is done. Alternatively a few drops of MnSo4 can be added..
the reaction is.
2MnO4- + 16H + 5 (C2O4)2-----:10CO2 + 2 Mn2+ + 8H2O
