Question

The electrochemical cell stops working after some time because:


  1. electrode potentials of both electrodes becomes zero
  2. electrode potentials of both electrodes becomes equal
  3. temperature of the cell increases
  4. the reaction starts proceeding in opposite direction

A
the reaction starts proceeding in opposite direction
B
electrode potentials of both electrodes becomes equal
C
electrode potentials of both electrodes becomes zero
D
temperature of the cell increases
Solution
Verified by Toppr

Due to the potential difference between electrode,electrons flow from one electrode to another.After some time there is no potential difference between electrodes i.e. electrode potential becomes equal.
