The number of mole of `KMnO_(4)` that will be needed to react completely with one mole of ferrous oxalate in acidic solution is:

Options

A. `3//5`
B. `2//5`
C. `4//5`
D. `1`

Answer

1

Explanation

This reaction is slow at room temperature but it rapid at `60^(@)C`.
`2MnO_(4)^(-)+16H^(+)+5C_(2)O_(4)^(2-)overset(60^(@)C)rarr2Mn^(2+)+8H_(2)O+10CO_(2)`
