The equivalent conductance of NaCl at concentration C and at infinite dilution are λ C and λ ∞ , respectively. The correct relationship between λ C and λ ∞ is given as : (where the constant B is positive)

Options

  1. Aλ C = λ ∞ + B C
  2. Bλ C = λ ∞ - B C
  3. Cλ C = λ ∞ - B C
  4. Dλ C = λ ∞ + B C

Correct answer

C. λ C = λ ∞ - B C

Step-by-step solution

By Debye Huckel Equation Λ m c = Λ m ∘ - A + B Λ m ∘ C Dividing by Z Factor of Electrolyte Λ m c z = Λ m ∘ z - A + B Λ m ∘ z C λ c = λ ∞ - B C
