Quizplus · Accepted Answer

For a reaction that is nonspontaneous at low temperatures but becomes spontaneous at high temperatures, the sign of the enthalpy change (ΔH) must be positive, and the change in entropy (ΔS) must also be positive. This is because the Gibbs free energy change (ΔG) becomes more negative as the temperature increases if ΔS is positive. This scenario fits the description of a reaction that is nonspontaneous at low temperatures (such as 25°C) but becomes spontaneous as the temperature increases.
