Ok, another late night bar question that I found perplexing, and here's hoping someone on this forum can address:
I think I'm accurate in stating that a single cell example of a battery is a chemical reaction producing electrons- A reduction rxn at the cathode & oxidation at the anode. The power capacity is dependent upon the volume of reagents present, the current capacity a function of the internal resistance (itself based on the surface area & size of the electrodes & the proton conducting electrolyte, etc).
What determines the voltage of a single battery cell- the number of electrons produced by each unit of the reaction, the equilibrium point of the reaction, the activation energy, or some other factor?
