NEET Chemistry Nernst Equation Assertion Reason Question
Assertion (A): The cell potential of a Daniell cell increases with an increase in the concentration of Cu²⁺ ions. | Reason (R): In a Daniell cell, the Nernst equation shows that the cell potential is inversely proportional to the concentration of Zn²⁺ ions.
Both (A) and (R) are true, and (R) is the correct explanation of (A).
Both (A) and (R) are true, but (R) is not the correct explanation of (A).
(A) is true, but (R) is false.
(A) is false, but (R) is true.
Correct Answer
Detailed Explanation
The Nernst equation shows that the cell potential increases with an increase in Cu²⁺ concentration and decreases with an increase in Zn²⁺ concentration, explaining the assertion.
