JEE Mains · Chemistry · STD 12 - 2. Electrochemistry

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 \((iv)\) \(\Omega^{-1} \,\mathrm{~m}^{-1}\)
Choose the most appropriate answer from the options given below :

  1. A \((\mathrm{a})-(\mathrm{iii}),(\mathrm{b})-(\mathrm{i}),(\mathrm{c})-(\mathrm{iv}),(\mathrm{d})-(\mathrm{ii})\)
  2. B \((\mathrm{a})-(\mathrm{iii}),(\mathrm{b})-(\mathrm{i}),(\mathrm{c})-(\mathrm{ii}),(\mathrm{d})-(\mathrm{iv})\)
  3. C \((a)-(i), (b)-(iv), (c)-(iii), (d)-(ii)\)
  4. D \((a)-(ii), (b)-(i), (c)-(iii), (d)-(iv)\)
Verified Solution

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…
