Oxalic acid is oxidised by a acidified `KMnO_(4)` as follows:
`2MnO_(4)^(-)+16H^(+)+5C_(2)O_(4)^(2-)to2Mn^(2+)+10CO_(2)+8H_(2)O`
The rate of this reaction increases with time because

Options

A. `CO_(2)` formed escapes
B. of presence of sulphuric acid `[H^(+)]`
C. Of formation of `Mn^(2+)` which acts an anto catalyst
D. `KMnO_(4) ` is a strong oxidizing agent

Answer

C

Explanation

`Mn^(2+)` acts as self catalyst
