The standard cell potential is the emf measured when you connect two half-cells together under standard conditions. The standard electrode potential is actually a special case of a standard cell potential where one of the half-cells is a hydrogen electrode. You can also imagine a cell made up of two half-cells like this:

Electrolytic cells – Electrical energy is consumed to bring about a chemical reaction or a chemical change. Galvanic cells – Also called voltaic cells where chemical energy is converted into electrical energy. In daniel cell current flows from copper electrode to the zinc electrode. Under Standard condition, it generates an emf of 1.1V.

As seen from equation (4.6), the cell potential E corresponds to the standard cell potential E0, För ovanstående cell med halvreaktionen Fe3+/Fe2+ fås standard-elektrodpotentialen +0.77 V. En positiv potential innebär att jämvikt av reaktionen Fe3+/Fe2+ Electrochemical Cell Potentials.

The cell potentialfor a voltaic cellunder standard conditions can be calculated from the standard electrode potentials. But real voltaic cells will typically differ from the standard conditions. The Nernst equation relates the cell potential to its standard cell potential. R = gas constant

The cell would therefore proceed spontaneously in Case 2.Notice that we did not multiply the value for the reduction potential of I 2 by a factor of 2, even though the iodine reduction equation would be multiplied by this factor to balance the number of electrons produced and consumed.
