When a concentrated solution of an electrolyte is diluted

On diluting the solution of an electrolyte

As the dilution of an electrolyte increases

Define conductivity and molar conductivity for the solution of an electrolyte. How do they vary when the concentration of electrolyte in the solution increases ?

When a solution of weak electrolyte is heated the conductance of the solution

Why is the molar conductivity at infinite dilution greater than the molar conductivity at any other concentration of an electrolyte at a given temperature ?
