Overall reaction does not involve any ion in solution whose concentration can change during its life time.

Q. Assertion : In mercury cell, the cell potential is approximately 1.35V and remains constant during its life. Reason : The overall reaction in mercury cell is represented as Zn(Hg)+HgO(s)​→ZnO(s)​+Hg(l)​

If both assertion and reason are true and reason is the correct explanation of assertion

If both assertion and reason are true but reason is not the correct explanation of assertion

If assertion is true but reason is false

If both assertion and reason are false

Overall reaction does not involve any ion in solution whose concentration can change during its life time.

Q. Assertion : In mercury cell, the cell potential is approximately $1.35 V$ and remains constant during its life.
Reason : The overall reaction in mercury cell is represented as $Z n (H g) + H g O_{(s)} \to Z n O_{(s)} + H g_{(l)}$
