Question

What is a key difference between an electrolytic cell and a voltaic cell
A.
The anode is assigned the negative charge.
B.
The anode is assigned the positive charge.
C.
The electrodes are connected with a wire.
D.
The electrons move from the anode to the cathode.
E.
There are two half-reactions.

Answer 1

In electrolytic cell , the anode is assigned to the positive electrode while in voltaic cell , cathode is assigned to the positive electrode .

In electrolytic cell , electron flow from cathode to anode while in voltaic cell , electrons flow from anode to cathode .

So your answer would be D
