Question

in electrochemistry if emf of cell is difference between the electrodes then why do we sum up Eop and Erp? we usually subtract for difference.
EMF of cell = Eop + Erp
plz answer sincerely otherwise I will report you.​

Answer 1

Answer:

The voltage or electric potential difference across the terminals of a cell when no current is drawn from it. The electromotive force (emf) is the sum of the electric potential differences produced by a separation of charges (electrons or ions) that can occur at each phase boundary (or interface) in the cell.
