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)
