Which of the following incorrectly pairs the electrochemical physical quantity with its standard or — Electrochemistry Chemistry Question

💡 Solution & Explanation

Specific conductance (conductivity, $\kappa$) is defined as conductance times the cell constant. Its unit is $S\text{ cm}^{-1}$ or $S\text{ m}^{-1}$ (Ohm $^{-1}$ cm $^{-1}$). The unit $S\text{ cm}^2\text{ mol}^{-1}$ correctly belongs to molar conductance ($\Lambda_m$), not specific conductance.
