For solid A,

\Delta H^{\circ}_{\text{diss}} = -10\,\text{kJ mol}^{-1}

and

\Delta S^{\circ}_{\text{diss}} = -40\,\text{J mol}^{-1}\,\text{K}^{-1}

. For solid B,

\Delta H^{\circ}_{\text{diss}} = +10\,\text{kJ mol}^{-1}

and

\Delta S^{\circ}_{\text{diss}} = +40\,\text{J mol}^{-1}\,\text{K}^{-1}

. Both solids are sparingly soluble at

0^{\circ}\text{C}

. When the temperature is raised to

60^{\circ}\text{C}

, which solid is expected to show the larger increase in solubility? Briefly explain your choice.
