What do you understand by standard e.m.f. of a cell ? Derive a relationship between standard emf of a cell and equilibrium constant.

Answer» Standard emf of a cell is the difference in the standard reduction potentials of cathode and anode when no current flows through the cell. For the relationship between standard emf `(E_(cell)^(@))` are equilibrium constant`(K_(c))`, consult Section 9.11.
