Which of the following is a type of electrochemical cell used to produce electrical energy from a spontaneous chemical reaction?

  1. Electrolytic cell
  2. Galvanic cell (voltaic cell) āœ“
  3. Fuel cell
  4. Electroplating cell

Explanation

A galvanic cell converts chemical energy into electrical energy through spontaneous redox reactions. Common batteries like AA and car batteries are galvanic cells.

The cell contains two different metals in solutions that allow electrons to flow through a wire. This electron flow creates electric current that can power devices.

Electrolytic cells do the opposite by using electrical energy to drive non-spontaneous reactions. Galvanic cells generate electricity while electrolytic cells consume it.
