Q. Statement 1: For a cell reaction
at the equilibrium,voltmeter gives zero reading.
Statement 2: At the equilibrium, there is no change in the concentration of and .

Solution:

As the time passes, the concentration of keeps on increasing while the concentration of keeps on decreasing. At the same time voltage of the cell keeps on decreasing. When there is no change in concentration of and ions, voltmeter gives zero reading and this state is known as equilibrium.
