Waec Model Questions Vol1 2018 Chemistry Question 24
Practice objective / multiple choice question 24 from the 2018 Waec Model Questions Vol1 Chemistry examination.
In a galvanic cell the half‑reactions are:\nAnode (oxidation): Fe²⁺ → Fe³⁺ + e⁻ (E° = +0.77 V for Fe³⁺/Fe²⁺ reduction)\nCathode (reduction): MnO₄⁻ + 8 H⁺ + 5 e⁻ → Mn²⁺ + 4 H₂O (E° = +1.51 V)\nThe cell operates at 25 °C with [Fe²⁺]=0.010 M, [Fe³⁺]=0.10 M, [MnO₄⁻]=0.0010 M, [Mn²⁺]=0.10 M and [H⁺]=0.10 M. Calculate the cell potential E_cell under these conditions.
