Alternative derivation of the previous equation.
a) H₂ + 2·H₂O → 2·H₃O⁺ (pH=7, -0.42 V)
b) 4·OH^– → O₂ + 2·H₂O (pH=7, 0.83V)
The reaction would be mountaintop or lower left to upper right. the whole reaction with the indication that the reaction ·2 should be made.
The second question … [translation unavailable] ·2

Solution:

1. a) H₂ + 2·H₂O → 2·H₃O⁺ ( + 2·e^– )
2. b) 4·OH^– → O₂ + 2·H₂O ( + 4·e^– )
3. (b) + 2·a, rock reaction, electron balance
       4·OH^– + 4·H₃O⁺ → 2·H₂ + 4·H₂O + O₂ + 2·H₂O
       4·(OH^– + H₃O⁺) → 2·H₂ + O₂ + 6·H₂O
       4·( 2·H₂O ) → 2·H₂ + O₂ + 6·H₂O // – 6·H₂O
       2·H₂O → 2·H₂ + O₂
