Question Stem for Question Nos. 26 and 27

At 298K, the limiting molar conductivity of a weak monobasic acid is 4×102Scm2mol−1. At 298K, for an aqueous solution of the acid the degree of dissociation of α and the molar conductivity is boldsymbol‌y×102Scm2mol−1. At 298K, upon 20 times dilution with water, the molar conductivity of the solution becomes 3y×102Scm2mol−1.
