The chemical reaction represented by the following balanced chemical equation takes place in aqueous
solution: MnO4 + 5 Fe2+8H - Mn2 + 5 Fe3+ 4H2O
When the disappearance of the permanganate ion, MnO4, is monitored, the rate of reaction for the
consumption of the ion is 4.0x10^2 mol/L. s. Calculate the reaction rate for all other reactants and products.
