Chemistry - Electrochemistry Question with Solution | TestHub

Both$\mathrm{N}\mathrm{a}\mathrm{C}\mathrm{l}$and$\mathrm{K}\mathrm{C}\mathrm{l}$are strong electrolytes and as$\text{N}{\text{a}}^{+}$(aq) has less conductance than${\mathrm{K}}^{+}$(aq) due to more hydration of$\text{N}{\text{a}}^{+}$(g) due to small size and more hydration energy therefore the graph of option (B) is correct here.
Extent of hydration$\propto \frac{1}{{\mathrm{\Lambda }}_{\mathrm{m}}}$
