A student monitors the disappearance of a dissolved dye, represented by \(\text{D(aq)}\), at constant temperature and light intensity. The student constructs the three plots shown.

In a second trial under the same conditions, the student changes the initial dye concentration from \(0.500\ \text{M}\) to \(0.250\ \text{M}\). Based on the graphs, what is the half-life of \(\text{D(aq)}\) in the second trial?
