Electrochemistry Part 1

Limiting molar conductivity of KCl
Λm°‌KCl=Λm∞(K+)+Λm∞(Cl−)
=73.55S‌cm2∕mol+76.3S‌cm2∕mol
=149.3S‌cm2∕mol
Limiting molar conductivity of CH3‌COOH
=349.8S‌cm2∕mol+40.9S‌cm2∕mol =390.7S‌cm2∕mol
∴ Limiting molar conductivity of CH3‌COOH is more than KCl.
Hence, statement I is false.
Also, as the concentration decreases, dilution of the electrolyte increases which will increase the degree of dissociation of weak electrolyte. Thus, the number of ions in the solution increases and hence, the molar conductance of electrolyte increases. Therefore, we can see that with decrease in concentration of electrolyte, molar conductance increases.
Hence, statement II is also false.
