Explain, in terms of electrical energy, how the operation of a voltaic cell differs from the operation of an electrolytic cell used in the Hall process. Include both the voltaic cell and the electrolytic cell in your answer.

Would this be correct:
In a voltaic cell, chemical energy is spontaneously converted to electrical energy. in an electrolytic cell, the reaction cannot occur spontaneously; there must be some electrical generator placed into the circuit to force the electrons to flow from the anode to the cathode.

    The first sentence is very good. The second one is a little sparse. I would suggest changing the words anode and cathode to avoid confusion caused by which is the negative electrode and which is the positive electrode.
