Question

17 multiple choice 2 points if a reaction is exothermic, then _____. δs°<0 δh°>0 δs°>0 δh°<0 both b and d previous

Explanation:

An exothermic reaction releases heat. By definition, for an exothermic reaction, the change in enthalpy $\Delta H^{\circ}<0$. Entropy change $\Delta S^{\circ}$ is not determined by whether a reaction is exothermic or endothermic.

Answer:

D. $\Delta H^{\circ}<0$
