Question
The equivalent conductance of NaCl at concentration C and at infinite dilution are λC and λ∞ respectively. The correct relationship between λC and λ∞ is given as
(Where the constant B is positive)
(Where the constant B is positive)
Options
A.λC = λ∞ + (B)C
B.λC = λ∞ - (B)C
C.λC = λ∞ - (B)√C
D.λC = λ∞ + (B)√C
Solution
According to Debye Huckle onsager equation,
λC = λ∞ - A√C
Here A = B
∴ λC = λ∞ - B√C
λC = λ∞ - A√C
Here A = B
∴ λC = λ∞ - B√C
