Question

An electrolysis experiment is stopped and the battery terminals are reversed.
(a) The electrolysis will stop.
(b) The rate of liberation of material at the electrodes will increase.
(c) The rate of liberation of material will remain the same.
(d) Heat will be produced at a greater rate.

Answer 1

Answer:

d. the electrolysis will stop

Answer 2

(c) When the battery terminals are reversed and the electrolysis experiment is stopped, the liberation rate of the material will always be the same.

Explanation:

• The non-spontaneous redox reaction is driven by the electrolytic cell, which is an electrochemical cell.  
• Both the electrodes are made up of the same material in an electrolytic cell. Thus, when the battery is reversed, the flow of charges direction will be reversed. But the electrolysis rate will always be the same.
