Which of the following statements about voltaic and electrolytic cells is correct? Group of answer choices The electrons in the external wire flow from cathode to anode in an electrolytic cell. The free energy change, ΔG, is negative for the voltaic cell. The anode will definitely gain weight in a voltaic cell. Oxidation occurs at the cathode of both cells. None of these statements is correct.

The free energy change, ΔG, is negative for the voltaic cell.

Explanation:

One major difference between an electrolytic cell and a voltaic cell is that a voltaic cell produces energy from a spontaneous chemical process while an electrolytic del! Produces energy from a non spontaneous chemical process.

Given a spontaneous chemical process, ∆G is always negative as in a voltaic cell. How ever, in a non spontaneous electrolytic cell, ∆G is positive.

This is the major difference between a voltaic cell or and an electrolytic cell.
