$D$. Molar conductivity decreases sharply with increase in concentration.

Vedclass · Answer

(D) For a weak electrolyte,the degree of dissociation increases as the concentration decreases (dilution increases). At very low concentrations (near infinite dilution,where $\sqrt{C} 	o 0$),the degree of dissociation increases rapidly,leading to a sharp increase in molar conductivity. Conversely,as the concentration increases (moving away from the y-axis),the degree of dissociation decreases,causing a sharp decrease in molar conductivity. Therefore,the graph shows that molar conductivity decreases sharply with an increase in concentration.

When the molar conductivity of a weak electrolyte is plotted against the square root of its concentration $(\sqrt{C})$,which of the following is observed?
