In dilute aqueous H2SO4{H}_{2}S{O}_{4} , the complex diaquodioxalatoferrate (II) is oxidized by MnO4−{MnO}_{4}^{-} . For this reaction, the ratio of the rate of change of [H+]\left[{H}^{+}\right] to the rate of change of [MnO4−][ {MnO}_{4}^{-} ] is

Correct answer

8

Step-by-step solution

8H++MnO4−+[Fe(H2O)2(OX)2]2−⟶Mn2++Fe3++4CO2+6H28{H}^{+} + {MnO}_{4}^{-} + {\left[Fe{\left({H}_{2}O\right)}_{2}{\left(OX\right)}_{2}\right]}^{2 -} ⟶ M{n}^{2 +} + F{e}^{3 +} + 4C{O}_{2} + 6{H}_{2}
Rateofchangeof[H+]Rateofchangeof[MnO4−]=8\dfrac{Rateofchangeof [ {H}^{+} ]}{Rateofchangeof [ {MnO}_{4}^{-} ]} = 8
