Could someone please elaborate upon the difference between potential difference and EMF? Is EMF simply the maximum potential difference the battery can have before any reaction occurs? Or am I missing something? Thank you!
Standard reduction potential (E°) is an intensive property that gives the voltage difference between the anode and cathode (see course reader page 47). EMF is the cell potential, which is the maximum voltage actually generated; it is denoted by Ecell.
Emf is the maximum potential difference between the two electrodes ( cathode/anode) when no current is flowing in the circuit. Potential difference is the difference between the electrode potentials when current is flowing.
