Question

Match List-I with List-II

List-I (Parameter)		List-II(Unit)
a	Cell constant	i	$Sc{m}^{2}mo{l}^{-1}$
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 $=S{m}^{2}mol{e}^{-1}$
Conductivity $(K)\Rightarrow$ Units $=S{m}^{-1}$
Degree of dissociation $(\alpha )\to$ Dimensionless
$\therefore$ (a) $-$ (iii)
(b) - (i)
(c) - (iv)
(d) - (ii)
