### galvanic vs electrolytic

What's the difference between galvanic and electrolytic cells?

### Re: galvanic vs electrolytic

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.

### Re: galvanic vs electrolytic

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.

### Re: galvanic vs electrolytic

Galvanic Cell and Electrolytic Cells are essentially opposites

Galvanic Cell = $-\Delta G = spontaneous = +E^{\circ} cell = k<1$

Electrolytic Cell = $+\Delta G = nonspontaneous = -E^{\circ} cell = k>1$

### Re: galvanic vs electrolytic

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

### Re: galvanic vs electrolytic

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

### Re: galvanic vs electrolytic

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.

Electrolytic cells - non-spontaneous, convert electric energy into chemical energy

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