Question

Following figure shows dependence of molar conductance of two electrolytes on concentration. Λo m is the limiting molar conductivity. The number of incorrect statement(s) from the following is ________
(A) $\Lambda \text{o m}$ for electrolyte A is obtained by extrapolation.
(B) For electrolyte B, $\Lambda \text{m}$ vs c graph is a straight line with intercept equal to o $\Lambda \text{m}$
(C) At infinite dilution, the value of degree of dissociation approaches zero for electrolyte B.
(D) Λo m for any electrolyte A or B can be calculated using $\lambda0$ for individual ions.

Answer 1

The correct answer is 2
(A) Λo m for ‘A’ cannot be obtained by extra polation. (C) At infinite dilution, value of degree of dissociation approaches one.
therefore A and C are incorrect
