Statement I : At moderate concentrations molar conductivity of KCl is greater than that of CH3COOHStatement II : At moderate concentrations, KCl completely ionizes whereas CH3COOH undergoes incomplete ionisation

aq. KCl is a strong electrolyte and aq CH3COOH is a weak electrolyte.A strong electrolyte completely ionizes even at moderate concentration where as a weak electrolyte cannot completely ionise even at infinite dilution.Thus at moderate concentrations KCl(aq) is a better conductor than CH3COOH(aq).Statement I and II are correct.
