Question

Quizplus · Accepted Answer

For a reaction to be product-favored at low temperatures but not at high temperatures, ΔH should be negative (exothermic) and ΔS should be negative. At low temperatures, the negative ΔH dominates, making ΔG negative, but at high temperatures, the TΔS term becomes significant, making ΔG positive.
