In dilute aqueous `H_(2)SO_(4)` the complete diaquadioxalatoferrate (II) is oxidised by `MnO_(4)^(-)`. For the reaction, the ratio of the rate of change of `[H^(+)]` to the rate of change of `[MnO_(4)^(-)]` is

Answer» Correct Answer - 8
`8H^(+)+MnO_(4)^(-)+[Fe(H_(2)O)_(2)(OX)_(2)]^(2-) rarr Mn^(2+)+Fe^(3+)+4CO_(2)+6 H_(2)O`
`("rate of change of "[H^(+)])/("rate of change of "[MnO_(4)^(-)])=8`
