QJEEM14Chf8b5: JEE Main 2014 Chemistry - Class 12 JEEM14Chf8b5 Solution: The equivalent conductance of NaCl at concentration C and at…

The equivalent conductance of NaCl at concentration C and at infinite dilution are λC{\lambda _C} and λ∞{\lambda _\infty } , respectively. The correct relationship between λC{\lambda _C} and λ∞{\lambda _\infty } is given as: (where the constant B is positive)

Multiple Choice Options

  • A λC=λ∞+(B)C{\lambda _C} = {\lambda _\infty } + (B)C
  • B λC=λ∞−(B)C{\lambda _C} = {\lambda _\infty } - (B)C
  • C λC=λ∞−(B)C{\lambda _C} = {\lambda _\infty } - (B)\sqrt C
  • D λC=λ∞+(B)C{\lambda _C} = {\lambda _\infty } + (B)\sqrt C

Step-by-Step Verified Solution

According to Debye Huckle onsager equation,

                         λC=λ∞−BC\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,{\lambda _C} = {\lambda _\infty } - B\sqrt C
