Why on dilution the $Λ_{m}$ Of CH₃COOH increases drastically, while that of CH₃COONa increases gradually?

In the case of CH₃COOH, which is a weak electrolyte, the number of ions increase on dilution due to an increase in degree of dissociation.

{CH}_{3} COOH + H_{2} O ⇌ {CH}_{3} {COO}^{-} + H_{3} O^{+}

In case of strong electrolyte, the number of ions remains the same but the interionic attraction decreases,
