NEET Chemistry (general) Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 12
Assertion (A): Molar conductivity increases with dilution for both strong and weak electrolytes. | Reason (R): At infinite dilution, the molar conductivity of an electrolyte is the sum of the contributions of its individual ions.
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 B
Detailed Explanation
Molar conductivity increases with dilution because the ions have more space to move, leading to higher conductivity per mole of electrolyte. Kohlrausch's law gives the reason for the molar conductivity at infinite dilution, not for its increase with dilution.
