Surface Area of Electrodes

Postby Hannah Guo 3D » Tue Feb 20, 2018 8:02 am

When the surface area of the electrodes increases, the rate of redox reaction is supposed to increase, but will this change affect the values of E and E°?

Thank you!

Increasing surface area generally won't increase E and E°, since they depend on the substances making up the electrodes, not how much there is.
