Match List-I with List-II
List-I - List-II
(Parameter) (Unit)
(a) Cell constant → (i) S cm2mol-1
(b) Molar conductivity → (ii) Dimensionless
(c) Conductivity → (iii) m-1
(d) Degree of dissociation → (iv) Ω-1 m-1 of electrolyte
Choose the most appropriate answer from the options given below :
(1) (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)
(2) (a)-(iii), (b)-(i), (c)-(ii), (d)-(iv)
(3) (a)-(i), (b)-(iv), (c)-(iii), (d)-(ii)
(4) (a)-(ii), (b)-(i), (c)-(iii), (d)-(iv)
Correct answer: (1) (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)
Explanation:
Cell constant = \(\Big(\frac{\ell}{A}\Big)\)
⇒ Unit = m-1
Molar conductivity (∧m ) ⇒ Units = Sm2 mole-1
Conductivity (K) ⇒ Units = S m-1
Degree of dissociation (α) → Dimensionless
∴ (a) – (iii)
(b) – (i)
(c) – (iv)
(d) – (ii)
