Q.
The equivalent conductance of $NaCl$ at concentration $C$ and at infinite dilution are $\lambda_{c}$ and $\lambda_{\infty}$ given as
Electrochemistry
Solution:
Debye-Huckel Onsager equation can be written as
$\lambda_{c}=\lambda_{\infty}-b\sqrt{C}$
Where
$\lambda _c$ = Molar conductivity of the solution at certain concentration
$\lambda _{\infty }$ = Limiting molar conductivity
$C$ = Concentration
$b$ = Constant that depends on temperature, charges on the ions and dielectric constant as well as viscosity of the solution
