Answer:
is
a strong electrolyte. At high concentration, there are greater number of ions
per unit volume which increases attraction between 
and 
ions. If
solution is diluted, then it decrease in ionic attractions, hence molar conductivity
increases with dilution, on regular basis.
On the other hand, 
is a
weak acid. By Ostwald's dilution law, degree of ionization (x) is related to
dilution by 
[1]
In higher concentration range, ionisation is very small,
thus molar conductance, also remains constant. In lower concentration range
(very dilute solution) ionisation is rapid, hence molar conductance
increases rapidly with dilution.
