(a) Solution A has the higher percent ionization and the higher pH.

Work Step by Step

Solution B has a higher initial concentration of $HNO_2$ than solution A. With higher initial concentration of acid, we get more concentration of $H_3O^+$. With lower initial concentration of acid, we also get a higher percent ionization due to Le Chatelier's Principle, and the inverse is also true. Thus, Solution B has a lower pH and lower percent ionization, and Solution A has the opposite.
