Q.Distinguish between electrolytic and galvanic cells.

Step 1. An electrolytic cell consumes electrical energy from an external DC source to force an otherwise NON-spontaneous reaction (electrolysis) to occur, converting electrical energy into chemical energy; its anode is positive and cathode negative, fixed by the battery's terminals.

Step 2. A galvanic (voltaic) cell instead runs a SPONTANEOUS chemical reaction on its own, converting chemical energy into electrical energy that it supplies to an external circuit; its anode is negative and cathode positive, fixed by the electrode reactions themselves, not an external source. …

Contrast the two cell types on spontaneity, energy-conversion direction, and elec …

• Assuming anode is always negative or always positive regardless of cell type -- the polarity is opposite between electrolytic and galvanic cells, even tho …
