JEE Main 2023 — Electrochemistry Question with Solution

Following figure shows dependence of molar conductance of two electrolytes on concentration. $$\Lambda \stackrel{o}{m}$$ is the limiting molar conductivity.

The number of $$\underline{\mathrm{incorrect}}$$ statement(s) from the following is ___________

(A) $$\Lambda \stackrel{o}{m}$$ for electrolyte A is obtained by extrapolation

(B) For electrolyte B, $$\Lambda m$$ vs $$\sqrt{c}$$ graph is a straight line with intercept equal to $$\Lambda \stackrel{o}{m}$$

(C) At infinite dilution, the value of degree of dissociation approaches zero for electrolyte B.

(D) $$\Lambda \stackrel{o}{m}$$ for any electrolyte A and B can be calculated using $${\lambda }^{\circ }$$ for individual ions
