What happens when opposing voltage applied to the Galvanic cell reaches 1.1 V? I. Reactions stop together. II. No current flows through the cell. III. Rate of reaction increases. Which of the above statements is/are incorrect?
1 I and II
2 Only I
3 Only III
4 Only II
Explanation:
No current will flow through the cell and the reaction stops. So, the option (3) is correct.
