Draw the graph to show the variation of molar conductivity of a weak electrolyte with concentration.

Graph of molar conductivity ($\Lambda_m$) against $\sqrt{C}$ for a weak electrolyte ($\mathrm{CH_3COOH}$): a steeply falling curve that rises very sharply at very low concentration and flattens at higher concentration; it cannot be extrapolated to $\Lambda_m^\circ$.

Axes: $\Lambda_m$ (y) against $\sqrt{C}$ (x). Curve for weak electrolyte (CH3COOH): very steep rise at low concentration, falling and flattening to a nearly horizontal tail at higher concentration; dotted extension at the top showing it cannot be extrapolated.
