A student titrates a \(25.0\text{ mL}\) sample of an unknown weak monoprotic acid, \(\text{HA}\), with a \(0.10\text{ M}\) solution of \(\text{NaOH}\) at \(25\,^{\circ}\text{C}\). The resulting titration curve is shown below.

Based on the titration curve, which of the following correctly identifies the \(\text{p}K_a\) of \(\text{HA}\) and provides the correct chemical justification for why the \(\text{pH}\) at the equivalence point is greater than \(7.0\)?
