### ΔH?

Does ΔH tell you whether or not a reaction is endo/exothermic? If so, does a positive ΔH mean endo or exothermic? Also, will we have to know about endothermic/endothermic rxns for the quiz? (Specifically questions like Fall 2014 #6)

Positive value means endothermic. Negative value means exothermic.

No, that won't be on your quiz.
