ChemistryNEET 2021Conductance and Kohlrausch's law

Electrochemistry

The molar conductances of NaCl, HCl and CH3COONa\mathrm{CH_3COONa} at infinite dilution are 126.45, 426.16 and 91.0 S cm2 mol−191.0\ \mathrm{S\,cm^2\,mol^{-1}} respectively. The molar conductance of CH3COOH\mathrm{CH_3COOH} at infinite dilution is:

  1. A.201.28 S cm2 mol−1201.28\ \mathrm{S\,cm^2\,mol^{-1}}
  2. B.390.71 S cm2 mol−1390.71\ \mathrm{S\,cm^2\,mol^{-1}}✓
  3. C.698.28 S cm2 mol−1698.28\ \mathrm{S\,cm^2\,mol^{-1}}
  4. D.540.48 S cm2 mol−1540.48\ \mathrm{S\,cm^2\,mol^{-1}}

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
