Question

If ∧_m and ∧₀ are the molar conductivities of a weak electrolyte at concentration C and at zero concentration, then the dissociation constant K_a is given by :

(a) K_a = \(\frac{∧^2_m\times C}{∧_0-∧_m}\)

(b) K_a = \(\frac{∧^2_m\times C}{∧_0(∧_0-∧_m)}\) 

(c) K_a = \(\frac{∧^2_0\times C}{(∧_0-∧_m)}\) 

(d) K_a = \(\frac{∧_m\times C}{∧_0(∧_0-∧_m)}\) 

Answer 1

Option : (b) K_a = \(\frac{∧^2_m\times C}{∧_0(∧_0-∧_m)}\)
