A student prepares two different aqueous buffer solutions at \(25\ ^\circ\text{C}\), each with a total volume of \(100\text{ mL}\).

Buffer	\([\text{CH}_3\text{COOH}]\)	\([\text{CH}_3\text{COONa}]\)
\(\text{X}\)	\(0.10\text{ M}\)	\(0.10\text{ M}\)
\(\text{Y}\)	\(0.50\text{ M}\)	\(0.50\text{ M}\)

Which buffer solution has a greater capacity to resist a change in \(\text{pH}\) upon the addition of a small amount of a strong acid, and why?
