galvanic vs electrolytic

Postby Jacob Puchalski 1G » Sun Mar 08, 2020 7:56 pm

What's the difference between galvanic and electrolytic cells?

A galvanic cell has a positive Eocell value, and therefore the redox reactions and flow of e- is spontaneous. An electrolytic cell has a negative Eocell value, so the flow of electrons requires an external source of current to cause the redox reactions to occur.

For galvanic cells, spontaneous redox reactions convert the chemical energy to an electric energy. For electrolytic cells, non-spontaneous redox reactions convert the electric energy to a chemical energy.

A galvanic cell prodices electrical energy and an electrolytic cell produces chemical energy.

Galvanic Cell and Electrolytic Cells are essentially opposites

Galvanic Cell =

Electrolytic Cell =

Galvanic cells use spontaneous reactions. Electrolytic cells are non-spontaneous, meaning that energy is needed to force the reaction to happen.

A galvanic cell have a positive standard Ecell while an electrolytic cell have a negative standard Ecell and it is not spontaneous.

In a electrolytic cell, energy from an external power source is used to drive a normally non-spontaneous reaction. In a galvanic cell, chemical energy is converted into electrical energy. The redox reaction is spontaneous and the anode is negative and the cathode is the positive electrode.

Galvanic cells transforms energy from spontaneous redox reactions into electrical energy. Electrolytic cells convert electrical energy into chemical energy.

When Galvanic cells are brought up it helps me to immediately think of batteries to help me remember that Galvanic cells convert chemical energy into electrical energy.

galvanic cells have a positive standard E and are spontaneous while electrolytic cells have a negative standard E and are nonspontaneous.

Galvanic cells are cells that use spontaneous reactions. Electrolytic cells use non-spontaneous reactions.
