Question

What is a key difference between an electrolytic cell and a voltaic cell? A.) The anode is where the oxidation takes place. B.) The cathode is where the reduction takes place. C.) There are two half-reactions. D.) There is an outside energy source. E.) The electrons move from the anode to the cathode.

Answer 1

The answer is D because the electrolytic cell needs energy to run because the reaction between half-cells are not spontaneous.
