Question

which of the following is not an electrochemical cell?a​

Answer 1

Answer:

An electrolytic is an electrochemical cell that drives a non-spontaneous redox reaction through the application of electrical energy.

Answer 2

Which of the following is not a type of electrochemical cell?

A) Voltaic cell

B) Photovoltaic cell

C) Electrolytic cell

D) Fuel Cell

Answer:

Photovoltaic cell is not an electrochemical cell.

Therefore, option (B) is correct.

Explanation:

An electrochemical cell converts the electrical energy into chemical energy.

• A Voltaic or Galvanic cell is an electrochemical cell. It converts chemical energy into electrical energy. In this cell oxidation occurs at anode and reduction occurs at cathode.
• Photovoltaic cell is not an electrochemical cell. Photovoltaic cell converts solar energy into electrical energy with process is called photovoltaic effect.
• An Electrolytic cell is a type of electrochemical cell which is used to convert electrical energy into chemical energy. In this cell, the metallic electrodes are held apart from each other and in contact with electrolyte. The electricity is provided to occur the non spontaneous redox reaction.
• A fuel cell is an electrochemical cell that converts the chemical energy of a fuel into electricity.
