Answer :

(i) K → (d)

(ii) Λ_{m} → (c)

(iii) ɑ →(b)

(iv) Q → (a) I × t

(i) We know, Resistance (R) = ρ =

Or, R κ = = G*

Or, κ=

Where, ρ = Resistivity or specific resistance =

L= Distance between the electrodes = length

A= Area of cross section of the electrode

G*= = Cell constant

(ii) Molar conductivity, Λ_{m} is defined as the conductivity of electrolyte divided by the molar concentration of the electrolyte.

Mathematically,

Λ_{m} =

Where, κ= Conductivity of the solution

C= Concentration

(iii) Degree of dissociation, α is defined as the ratio of the molar conductivity at any concentration to the limiting molar conductivity of an electrolyte.

Mathematically,

α =

(iv) Electric charge, Q is defined as the product of the electrical current passed and the duration.

Mathematically, Q = I x T
