I'm doing a TPR practice passage in electrochemistry.
There is a reaction that takes in H+ with e- O2 to make H20. The reduction of oxygen is oxidizing a metal.
The question asks why increasing acidity increases the oxidation. I figured more H+ = more reactant, pushing the reaction to the right.
The answer given is: The reduction of oxygen is energetically more favorable as acidity increases.
I chose that because it's the best answer, but it bothers me that it says "energetically more favorable". I thought energetically more favorable means it changes the thermodynamics, which only temperature should be able to do. (Change the Keq)
Thoughts?
