A student investigates the dissolution of a sparingly soluble salt, \(\text{PbI}_2\text{(s)}\), in pure water at three different temperatures. The experimental data collected are shown in the table below.

Temperature (\(\text{K}\))	Molar Solubility (\(\text{mol}\cdot\text{L}^{-1}\))
\(283\)	\(1.2 \times 10^{-3}\)
\(298\)	\(1.7 \times 10^{-3}\)
\(313\)	\(2.5 \times 10^{-3}\)

The dissolution equilibrium is represented by the following equation:
\[ \text{PbI}_2(s) \rightleftharpoons \text{Pb}^{2+}(aq) + 2\,\text{I}^-(aq) \]

Which of the following claims about the standard enthalpy of dissolution, \(\Delta H^\circ_{\text{soln}}\), is best supported by the data?
