Q. The conductivity of four electrolytes $P , Q , R , S$ in ohm $^{-1} \,cm ^{-1}$ are as follows $P \left(5 \times 10^{-5}\right), Q \left(1 \times 10^{-10}\right), R \left(7 \times 10^{-8}\right); S \left(9.2 \times 10^{-3}\right)$. The one which offers highest resistance to the passage of electric current is

Electrochemistry

Solution:

Conductivity ( $K ), \kappa=\frac{1}{ R } \times$ Cell constant
$\left[\kappa \propto \frac{1}{R}\right] \longrightarrow $ Resistance
$(Q)$ has minimum conductivity so, maximum resistance
