Problem

A molecular solid has

\Delta H^{\circ}_{\text{diss}} = +25\,\text{kJ mol}^{-1}

and

\Delta S^{\circ}_{\text{diss}} = +75\,\text{J mol}^{-1}\,\text{K}^{-1}

. Determine the minimum temperature, in

^{\circ}\text{C}

, above which its dissolution becomes spontaneous under standard conditions.
