    Molar conductivity of a solution at a given concentration is the conductance of volume V of a solution containing 1 mole of the electrolyte kept between two electrodes with the area of cross-section A and distance of unit length. As a result, the conductivity of a solution decreases with dilution. For review on this topic, visit the page "Electrochemistry 3: Cell potentials and thermodynamics ". Then plug in given values to the Nernst formula. Reduction occurs at cathode.
