Match the following reduction processes with the number of Faradays required:

Solution & Step-by-step Explanation

1. H_{2} O to O_{2} : 2 H_{2} O \to O_{2} + 4 H^{+} + 4 e^{-} . For 1 mol of H_{2} O, 2 e^{-} are needed. (2 F). (A-I)2. MnO_{4}^{-} to Mn^{2 +} : Oxidation state changes from + 7 to + 2 . 5 e^{-} are needed. (5 F). (B-III)3. Ca^{2 +} to Ca : 1 mol requires 2 F . 1.5 mol requires 1.5 \times 2 = 3 F . (C-IV)4. FeO to Fe_{2} O_{3} : Fe^{2 +} \to Fe^{3 +} + e^{-} . 1 mol requires 1 F . (D-II)

Try it yourself before checking the explanation above.
