The molar conductivity of a solution of a weak acid\[HX\text{ }\left( 0.01\text{ }M \right)\] is 10 times smaller than the molar conductivity of a solution of a weak acid\[HY\text{ }\left( 0.10\text{ }M \right)\]. If \[\lambda _{{{X}^{-}}}^{0}\approx \lambda _{{{Y}^{-}}}^{0}\], the difference in their \[p{{K}_{a}}\] values, \[p{{K}_{a}}\left( HX \right)-p{{K}_{a}}\left( HY \right)\], is (consider-degree of ionization of both acids to be <<1)
