Question

What are the balanced equation, standard emf, ΔG°, and K value at 298 K for the oxidation of MnO₂(s) to MnO₄⁻(aq) by ClO⁻(aq) in basic solution?

Accepted Answer

balanced equation: 2 MnO₂(s) + 2 OH⁻(aq) + 3 ClO⁻ (aq) → 2 MnO₄⁻(aq) + H₂O(l) + 3 Cl⁻(aq)
E° = 0.30 V
ΔG° =−1.7×10² kJ
K = 3×10³⁰

Answer

balanced equation: MnO₂(s) + 2 OH⁻(aq) + ClO⁻ (aq) → MnO₄⁻(aq) + H₂O(l) + Cl⁻(aq)
E° = −0.30 V
ΔG° =1.7×10² kJ
K = 4×10⁻³¹
