Options

AA small decrease in molar conductivity is observed at infinite dilution.
BMolar conductivity decreases sharply with increase in concentration.
CA small increase in molar conductivity is observed at infinite dilution.
DMolar conductivity increases sharply with increase in concentration.

Correct answer

B. Molar conductivity decreases sharply with increase in concentration.

Step-by-step solution

For weak electrolyte, variation of

\wedge_m

with
