The following curve is obtained when molar conductivity `(wedge_(m))` is plotted against the square root of concentration, `c^(1//2)` for two electrolytes A and B
(a) How do you account for the increase in the molar conductivity of the electrolyte A on dilution.

(b) As seen from the graph, the value of limiting molar conductivity `(wedge_(m)^(0))` for electrolyte B cannot be obtained graphically. How can this value be obtained?1
