Question
- A. One of the reacting chemicals is used up.
- B. The metal wires permanently lose all conductivity.
- C. The electrolyte changes into an insulator instantly.
- D. The voltage increases until no reaction is possible.
Answer
One of the reacting chemicals is used up. When that happens, the non-rechargeable cell can no longer maintain a potential difference.
Explanation
One of the reacting chemicals is used up in a non-rechargeable cell, so the chemical reaction stops. Without that reaction, the cell stops transferring energy electrically to the circuit.
Common mistake
Misunderstanding Cell Composition
Students often think that cells only contain metals and do not recognize the role of electrolytes in producing electricity.
Emphasize that cells consist of two different metals and an electrolyte, which is crucial for the chemical reactions that generate electricity.
