Match List\(-I\) with List\(-II\):
| List\(-I\) (Parameter) | List\(-II\) (Unit) |
| \((a)\) Cell constant | \((i)\) \(\mathrm{S}\, \mathrm{cm}^{2} \,\mathrm{~mol}^{-1}\) |
| \((b)\) Molar conductivity | \((ii)\) Dimensionless |
| \((c)\) Conductivity | \((iii)\) \(\mathrm{m}^{-1}\) |
| \((d)\) Degree of dissociation of electrolyte | \((iv)\) \(\Omega^{-1} \,\mathrm{~m}^{-1}\) |
- A \((\mathrm{a})-(\mathrm{iii}),(\mathrm{b})-(\mathrm{i}),(\mathrm{c})-(\mathrm{iv}),(\mathrm{d})-(\mathrm{ii})\)
- B \((\mathrm{a})-(\mathrm{iii}),(\mathrm{b})-(\mathrm{i}),(\mathrm{c})-(\mathrm{ii}),(\mathrm{d})-(\mathrm{iv})\)
- C \((a)-(i), (b)-(iv), (c)-(iii), (d)-(ii)\)
- D \((a)-(ii), (b)-(i), (c)-(iii), (d)-(iv)\)
Answer & Solution
Correct Answer
(A) \((\mathrm{a})-(\mathrm{iii}),(\mathrm{b})-(\mathrm{i}),(\mathrm{c})-(\mathrm{iv}),(\mathrm{d})-(\mathrm{ii})\)
Step-by-step Solution
Detailed explanation
Cell constant \(=\left(\frac{\ell}{\mathrm{A}}\right) \Rightarrow\) Units \(=\mathrm{m}^{-1}\) Molar conductivity \(\left(\Lambda_{m}\right) \Rightarrow\) Units \(=\mathrm{Sm}^{2} \,\mathrm{~mole}^{-1}\) Conductivity \((\mathrm{K}) \Rightarrow\) Units…
