Question

Which of the following is consistent with an exothermic reaction that is nonspontaneous at high temperatures A)($\Delta$H) > 0,$\Delta$S < 0, $\Delta$G < 0 B)($\Delta$H) > 0, $\Delta$S > 0, $\Delta$G < 0 C)($\Delta$H) < 0, $\Delta$S > 0, $\Delta$G < 0 D)($\Delta$H) < 0, $\Delta$S > 0, $\Delta$G > 0 E)($\Delta$H) < 0, $\Delta$S < 0, $\Delta$G > 0

Quizplus · Accepted Answer

An exothermic reaction has $\Delta$H < 0. For it to be nonspontaneous at high temperatures, $\Delta$S must be negative, making $\Delta$G positive at high temperatures.
