Standard Cell Potentials

Postby Farah Ahmad 2A » Sun Feb 18, 2018 2:32 pm

If a half-reaction is multiplied by a value is the value of the Standard Cell Potential of the reaction affected?

No, unlike Hess's Law when you multiply a redox half reaction by a factor you do not also multiply the cell potential by that factor.

The standard cell potential is not changed because it is equal to deltaG/(n*F). Therefore, if you would double the reaction, you would end up doubling both deltaG and n, which would cancel out.

Is this because electrochemical reactions are intensive or is that incorrect?

yes it is because potentials are intensive properties

No, multiplying a half-reaction by a factor does not affect the Standard Cell Potential value
