Electrochemistry
Electrochemistry is the study of redox reactions that involve electric current, either producing electricity from a spontaneous reaction (a galvanic/voltaic cell) or using electricity to force a nonspontaneous reaction to occur (an electrolytic cell).
Electrochemical Cell
An electrochemical cell is a system with two half-reactions separated into electrodes and connected through an external circuit so electrons can flow.
Electrolytic Cell
An electrolytic cell uses an external power source to force a nonspontaneous redox reaction to occur. Electrical energy is converted into chemical change.
