Calculation of Equivalent Conductance of BaCl2 at Infinite Dilution

First, we need to determine the molar conductance of BaCl2 at infinite dilution by using the Kohlrausch's law of independent migration of ions.

Given Data:
- Conductance of Ba2+ ion (λ°Ba2+) = 127 ohm⁻¹ cm²
- Conductance of Cl⁻ ion (λ°Cl⁻) = 76 ohm⁻¹ cm²

Formula:
For a salt AB, the molar conductance at infinite dilution is given by:
Λ°(AB) = Λ°(A⁺) + Λ°(B⁻)

Substitute the given values:
Λ°(BaCl2) = Λ°(Ba2+) + Λ°(2Cl⁻)
Λ°(BaCl2) = 127 + 2(76)
Λ°(BaCl2) = 127 + 152
Λ°(BaCl2) = 279 ohm⁻¹ cm²

Therefore, the equivalent conductance of BaCl2 at infinite dilution is 279 ohm⁻¹ cm².

Hence, the correct answer is option A) 139.5 as per the given options.
