One of the differences between a voltaic cell and an electrolytic cell is that in an electrolytic cell . a. an electric current is produced by a chemical reaction b. electrons flow toward the anode c. a nonspontaneous reaction is forced to occur d. O2 gas is produced at the cathode e. oxidation occurs at the cathode

Voltaic cells convert chemical energy to electrical energy by means of an oxidation-reduction reaction. Electrolytic cells convert electrical energy to chemical energy, so they are the opposite of voltaic cells. They require an input of electrical energy to cause an oxidation-reduction reaction

Explanation:

A Galvanic cell converts chemical energy into electrical energy. An electrolytic cell converts electrical energy into chemical energy. Here, the redox reaction is spontaneous and is responsible for the production of electrical energy. I hope this is helpful.
