Specific conductivity is the conductance by an electrolytic solution of unit volume kept between 2 platinum electrodes of unit length .Thus it depends upon concentration of the solution.
As volume increases on dilution, therefore no. of ions per unit volume carrying the current decreases. So , specific conductivity too decreases.
While molar conductivity is the conductivity per molar solution. In other words , conductivity of 1mole of unit volume of electrolytic solution. Therefore on dilution molar conductivity increases.
k = l/AR
λm = k/M = kV/n
