17.7 Electrolysis – Chemistry

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 car pictured in the Chapter 18 Introduction at the beginning of this chapter shows one such process.
