the correct order is KCl > NaCl > LiCl .
explanation:- in case of Alkali metals ,
hydration energy decreases with increase atomic number e.g., order of hydration energy is Li+ > Na+ > K+ > Rb+ > Cs+ .
and we know, mobility is inversely proportional to hydration energy so,
order of mobility is Cs+ > Rb+ > K+ > Na+ > Li+
now, equivalent conductance is directly proportional to mobility .
that's why order of equivalent conductance is K+ > Na+ > Li+
hence, order of equivalent conductance is KCl > NaCl > LiCl
