Molar conductivity of 0.02 M weak acid is 7.92 ⁻¹ ~cm ^2 ~mol ⁻¹ and its molar conductivity at infinite dilution is 232.7 ⁻¹ ~cm ^2 ~mol ⁻¹ . Calculate degree of dissociation of weak acid.

Options

  1. A0.0112
  2. B0.0341
  3. C0.0694
  4. D0.292

Correct answer

B. 0.0341

Step-by-step solution

Degree of dissociation ( )= _c ₀ = 7.92 ⁻¹ ~cm ^2 ~mol ⁻¹ 232.7 ⁻¹ ~cm ^2 ~mol ⁻¹ =0.0341
