Following figure shows dependence of molar conductance of two electrolytes on concentration. Λm0 is the limiting molar conductivity.

 

The number of Incorrect statement(s) from the following is _____

(A) Λm0 for electrolyte A is obtained by extrapolation
(B) For electrolyte B,   Λm Vs c  graph is a straight line with intercept equal to Λm0
(C) At infinite dilution, the value of degree of dissociation approach zero for electrolyte B.
(D) Λm for any electrolyte A or B can be calculated using λ° for individual ions.

Answer:
2
Solution:


Following are the correct versions of the two incorrect statements:
(A) Λm0 for electrolyte A is cannot be obtained by extrapolation as the curve for A is diverging away from the y-axis

(C) At infinite dilution, value of degree of dissociation approaches one for electrolyte B
