Vedclass · Answer

(A) The cell constant is defined as the ratio of the distance between electrodes $(\ell)$ to the area of cross-section $(A)$,so its unit is $m^{-1}$.Molar conductivity $(\Lambda_{m})$ is defined as the conductance of all ions produced from one mole of electrolyte,with units $S\, m^{2}\, mol^{-1}$ (or $S\, cm^{2}\, mol^{-1}$).Conductivity $(\kappa)$ is the reciprocal of resistivity,with units $\Omega^{-1}\, m^{-1}$ or $S\, m^{-1}$.Degree of dissociation $(\alpha)$ is the ratio of the number of moles dissociated to the total number of moles,which is a dimensionless quantity.Therefore,the correct matching is $a-iii, b-i, c-iv, d-ii$.

List-$I$ (Parameter)	List-$II$ (Unit)
$a$. Cell constant	$i$. $S\, cm^{2}\, mol^{-1}$
$b$. Molar conductivity	$ii$. Dimensionless
$c$. Conductivity	$iii$. $m^{-1}$
$d$. Degree of dissociation of electrolyte	$iv$. $\Omega^{-1}\, m^{-1}$
