Consider a reaction that has a negative ΔH and a negative ΔS.Which of the following statements is TRUE?

Question

Quizplus · Accepted Answer

A negative ΔH indicates that the reaction is exothermic and releases heat, while a negative ΔS indicates a decrease in disorder. For a spontaneous reaction, ΔG must be negative (ΔG = ΔH – TΔS). Therefore, at high temperatures, the negative entropy term becomes less important, and the reaction becomes nonspontaneous. Thus, this reaction will be nonspontaneous at high temperatures but may be spontaneous at low temperatures.
