Conductivity of an electrolyte is the conductance of 1cm3 of the given electrolyte. So, it increases with the increase of concentration of electrolyte. Molar conductivity is the conductance of a solution containing 1 mole of the electrolyte. It increases with the decrease of concentration (i) due to increase in interionic attraction for strong electrolytes and (ii) due to decrease in degree of ionization for weak electrolytes. Therefore, S1 is wrong and S2 is correct.
