NEET Chemistry (general) Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 12
Assertion (A): The limiting molar conductivity of an electrolyte can be determined by summation of individual ionic contributions. | Reason (R): The electrical resistance of an electrolyte solution is independent of its geometry.
A
Both (A) and (R) are true, and (R) is the correct explanation of (A).
B
Both (A) and (R) are true, but (R) is not the correct explanation of (A).
C
(A) is true, but (R) is false.
D
(A) is false.
Correct Answer
Option C
Detailed Explanation
Assertion (A) is true as per Kohlrausch's law, which states that the limiting molar conductivity of an electrolyte is the sum of the contributions of its ions. Reason (R) is false because resistance depends on the geometry of the electrolyte's container, as shown in the resistivity calculation.
