Question

The equivalent conductivity of 0.1 M weak acid is 100 times less than that at infinite dilution. The degree of dissociation of weak electrolyte at 0.1 M is (A) 100 (B) 10 (C) 0.01 (D) 0.001

Lambdav=( Lambda ° /100) So α =( Lambdav/ Lambda ° )=( Lambda ° /100 Lambda ° )=0.01

$Λ_{v} = \frac{Λ ^{\circ}}{100}$
So $α = \frac{Λ _{v}}{Λ ^{\circ}} = \frac{Λ ^{\circ}}{100 Λ ^{\circ}} = 0.01$

Λv​=100Λ∘​ So α=Λ∘Λv​​=100Λ∘Λ∘​=0.01

$Λ_{v} = \frac{Λ ^{\circ}}{100}$
So $α = \frac{Λ _{v}}{Λ ^{\circ}} = \frac{Λ ^{\circ}}{100 Λ ^{\circ}} = 0.01$
