Basic concept

From Kohlrausch's law, molar conductivity of an electrolyte can be expressed by following equation:

$\Lambda_{m} = \Lambda_{m}^{0}-\text{Kc}^{x},$

where $\Lambda_{m}$ is molar conductivity, $\Lambda_{m}^{0}$ is molar conductivity at infinite dilution, and $\text{K}$ is Kohlrausch constant and $\text{c}$ is concentration.

What is the appropriate value for $x?$
