For a solution of an electrolyte at a particular concentration and temperature, which of the following is not the function of cell constant?

1) specific conductance

2) molar conductance

3) equivalent conductance

4) conductance

The correct option is B 1, 2, 3
The conductance (G) of an electrolyte is equal to the reciprocal of its resistance (R). Hence, conductance is dependent of the cell constant$\left(\frac{l}{a}\right)$. Hence, statement 4 is incorrect.

$R=\frac{1}{G}=\frac{1}{k}\times \frac{l}{a}$

However, the specific conductance$\left(\kappa \right)$, the molar conductance and the equivalent conductance are not the functions of the cell constant.

Option B is correct.
