Faraday's equation electrolysis
WebOct 27, 2024 · 17.7: Electrolysis. In galvanic cells, chemical energy is converted into electrical energy. The opposite is true for electrolytic cells. In electrolytic cells, electrical energy causes nonspontaneous reactions to occur in a process known as electrolysis. The charging electric barttery shows one such process.
