Electrochemistry - Interactive Lesson

Interactive Course Summary

Galvanic and Electrolytic Electrochemical Cells — Electrochemistry investigates the interface between chemical transformations and electrical work. Galvanic (voltaic) cells harvest free energy from spontaneous redox reactions ($\Delta G < 0$) to generate electromotive force, while electrolytic cells supply external electrical potential to drive non-spontaneous reactions ($\Delta G > 0$).
