4. During space travel, oxygen O₂ is used for astronauts' breathing and as a fuel. It is constantly being produced onboard space crafts using water H₂O as the reactant in the following electrolysis reaction: 2H₂O (1)→ 2H2(g) + O₂(g) The two key half reactions are listed below as their reduction reactions: 2H₂O(1) +2e → H₂(g) + 2OH(aq) 2H₂O(1) + O₂(g) + 4c →40H (aq) a. What is the minimum potential to drive this reaction? b. A battery providing a constant current of 3.00 A is used for this electrolytic cell in the generation of O₂. What is the mass of Oz (in g) that is produced after running the battery for 1 hour? Use 32.0 g/mol for the molar mass of 0₂.

Transcribed Image Text:4. During space travel, oxygen O₂ is used for astronauts' breathing and as a fuel. It is constantly
being produced onboard space crafts using water H₂O as the reactant in the following
electrolysis reaction:
2H₂O (1)→ 2H2(g) + O₂(g)
The two key half reactions are listed below as their reduction reactions:
2H₂O(1) +2e → H₂(g) + 2OH(aq)
2H₂O(1) + O₂(g) + 4c →40H (aq)
a. What is the minimum potential to drive this reaction?
b. A battery providing a constant current of 3.00 A is used for this electrolytic cell in the
generation of O₂. What is the mass of Oz (in g) that is produced after running the
battery for 1 hour? Use 32.0 g/mol for the molar mass of 0₂.
