alleryThe molar conductivity Λ_m of an electrolyte:
AINCREASES on dilution for both strong and weak electrolytes
BEquals resistivity
CDecreases on dilution for strong electrolytes
DStays constant
Answer & Solution
Correct answer: A. INCREASES on dilution for both strong and weak electrolytes
Λ_m = κ/c (specific conductivity over concentration).
On dilution, ions move more freely (less ion-ion interaction for strong; more dissociation for weak), so Λ_m increases.
**At infinite dilution:** Λ_m^0 (limiting molar conductivity).
