JEE Advanced 2021 · Paper 2, Chemistry question 8

Question Stem for Question Nos. 7 and 8

At 298 K, the limiting molar conductivity of a weak monobasic acid is $4 \times 10^2$ S cm$^2$ mol$^{-1}$. At 298 K, for an aqueous solution of the acid the degree of dissociation is $\alpha$ and the molar conductivity is $\mathbf y \times 10^2$ S cm$^2$ mol$^{-1}$. At 298 K, upon 20 times dilution with water, the molar conductivity of the solution becomes $3\mathbf y \times 10^2$ S cm$^2$ mol$^{-1}$.
