I was wondering if someone would help me with my question. I was completing a question which asked about the effect of increased surface area of a platinum electrode on the EMF of the overall cell.
This is the cell: Pt | H2O2(aq), O2(g) || IO (aq), I2(aq) |Pt
When I answered, I thought the EMF would increase due to the surface area of the electrode being able to now accept more electrons but I found out the answer is that the EMF is unaffected by any change in surface area, why is this?
Thanks for any help anyone can provide!
