Why on dilution the molar conductivity of CH3COOH increases drastically,while that of CH3COONa increases gradually?

CH3COOH is a weak electrolyte while CH3COONa is a strong electrolyte.

CH3COOH, being a weaker electrolyte, upon dilution dissolves to a greater extent. Thus, the total volume containing 1 mol electrolyte also increases drastically, which leads to steep increase in molar conductivity.
CH3COONa on the other hand, is a stronger electrolyte. It is already extensively dissociated, and cannot dissociate more on dilution. Instead, only the mobility of the dissociated ions increase, and this increase leads to a gradual increase in the molar conductivity
