${\lambda _m} = {\lambda ^o}_m - K\sqrt c$; where ${\lambda ^o}_m$ is molar conductivity of electrolyte at infinite dilution, ${\lambda _a}$ is molar conductivity, $K =$ Kohlrausch coefficient, $c =$ concentration.
> We can determine the answer of this problem with the help of the above equation. For strong electrolyte molar conducting can be determined with the molar conductivity v/s concentration cure while for weak electrolyte it can not be determined by the curve. So from the above equation we can see that when concentration of electrolyte (which is represented by $c$ in the equation) decreases the value of molar conductivity will also be decreasing , Thus conductivity of an electrolyte solution decreases with the decrease in concentration.
