Chemistry
Given below are half cell reactions: MnO₄⁻ + 8H⁺ + 5e⁻ → Mn²⁺ + 4H₂O; Eº = −1.510 V ½ O₂ + 2H⁺ + 2e⁻ → H₂O; Eº = +1.223 V Will the permanganate ion, MnO₄⁻ liberate O₂ from water in the presence of an acid?
A
No, because Eºcell = − 2.733 V
B
Yes, because Eºcell = + 0.287 V
C
No, because Eºcell = – 0.287 V
D
Yes, because Eºcell = + 2.733 V
