For the redox reaction: a MnO_{4}^{-} + b C_{2} O_{4}^{2 -} + c H^{+} \to d Mn^{2 +} + e CO_{2} + f H_{2} O The correct coefficients of the reactants (a, b, c) for the balanced equation are:

Solution & Step-by-step Explanation

Balanced chemical equation using the ion-electron method: 2 MnO_{4}^{-} + 5 C_{2} O_{4}^{2 -} + 16 H^{+} \to 2 Mn^{2 +} + 10 CO_{2} + 8 H_{2} O Oxidation: C_{2} O_{4}^{2 -} \to 2 CO_{2} + 2 e^{-} (Multiply by 5)Reduction: MnO_{4}^{-} + 8 H^{+} + 5 e^{-} \to Mn^{2 +} + 4 H_{2} O (Multiply by 2)Coefficients a = 2, b = 5, c = 16 .
