The auto catalyst in the redox reaction involving acidified potassium permanganate and oxalic acid is
$\mathrm{Mn}^{2+}$
$\mathrm{SO}_4^{2-}$
$\mathrm{CO}_2$
$\mathrm{H}_2 \mathrm{O}$
Solution
$
5 \mathrm{C}_2 \mathrm{O}_4{ }^{2-}+2 \mathrm{MnO}_4{ }^{-}+16 \mathrm{H}^{+} \rightarrow
$
(Coloured)
$
\mathrm{Mn}^{2+}+8 \mathrm{H}_2 \mathrm{O}+10 \mathrm{CO}_2
$
(Colourless)
Formation of $\mathrm{Mn}^{2+}$ ions, which is indicated by the decrease in the intensity of the colour of the solution, the rate of the reaction increases which was slow initially
