The quantity of electricity required for the reduction of 1 mole of Fe2O3 to Fe is — Electrochemistry Chemistry Question

💡 Solution & Explanation

In Fe2O3, iron is in the +3 oxidation state. Reducing one $Fe^{3+}$ to $Fe(0)$ requires 3 electrons. Since 1 mole of Fe2O3 contains 2 moles of Fe atoms, it requires $2 \times 3 = 6$ moles of electrons, which equates to a charge of 6F. Therefore, correct answer is D.
