Question 4

What do electrolytic cells do?

Answer 4

Processes where non-spontaneous electrochemical
reactions are forced to occur using a power supply. These cells convert electrical energy (in the power supply) to chemical energy (in the products produced).

Question 5

The application of electrolytic cells is generally

industrial and includes but is not limited to: (3)

Answer 5

Answer 6

Spontaneous electron transfer is used to
create the basis of a power supply, i.e., a battery. Electrons spontaneously move from one species to another, through an external circuit, and in so doing, the cell creates electrical energy. In these cells, chemical energy is converted to electrical energy.
