(a) Define the following terms :
(i) Limiting molar conductivity,
(ii) Fuel cell
(b) Resistance of a conductivity cell filled with `0.1 molL^(-1)KCl` solution is 100 W. If the resistance of the same cell when filled with `0.2 mol L^(-1)KCl` solution is 520 W , calculate the conductivity and molar conductivity of `0.2 mol L^(-1) KCl` solution. The conductivity of `0.1 mol L^(-1) KCl` solution is ` 1.29xx10^(-1) W^(-1) cm^(-1)` .
