Question

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

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

(A)  for electrolyte A is obtained by extrapolation

(B) For electrolyte B,  vs  graph is a straight line with intercept equal to

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

(D)  for any electrolyte A or B can be calculated using  for individual ions.

Strategy:
 Identify the electrolyte types from the graph. Curve B (linear) is a strong electrolyte, while Curve A (non-linear, steep) is a weak electrolyte. Evaluate the statements based on these properties.

Statements Evaluation:
- (A)  for A (weak) by extra polation: Incorrect. For weak electrolytes, the curve never hits the y-axis linearly; it becomes infinite/undefined at  through extra polation.  must be found via Kohlrausch's Law. ✗
- (B) Curve B y-intercept: Correct. For strong electroly
