Question

Match List-I with List-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	iv	$\Omega^{-1}\, m^{-1}$

Choose the most appropriate answer from the options given below :

• A. (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)
• B. (a)-(iii), (b)-(i), (c)-(ii), (d)-(iv)
• C. (a)-(i), (b)-(iv), (c)-(iii), (d)-(ii)
• D. (a)-(ii), (b)-(i), (c)-(iii), (d)-(iv)

Answer 1

Answer: (A)

Cell constant $=\left(\frac{\ell}{ A }\right) $
$\Rightarrow $ Units $= m ^{-1}$
Molar conductivity $\left(\Lambda_{ m }\right) $
$\Rightarrow $ Units $= Sm ^{2} mole ^{-1}$
Conductivity $( K ) \Rightarrow $ Units $= S m ^{-1}$
Degree of dissociation $(\alpha) \rightarrow$ Dimensionless
$\therefore $ (a) $-$ (iii)
(b) - (i)
(c) - (iv)
(d) - (ii)
