Enhancement

Gibbs or Helmholtz free energy? Nope, haven't heard of it.

First off, allow me to introduce myself. I'm a student at the University of Waterloo in Waterloo, Ontario, Canada. I was in the International Development program for a couple years but left because it was a very poorly designed program. In the fall I will be starting the Biotechnology/Economics Co-Op program. Anyway, I've been reading my Cell Biology textbook to get a head start. Just finished the third chapter, which kept talking about "energetically favourable" and "energetically unfavourable" reactions. Is energetically favourable synonymous with exothermic? Is energetically unfavourable synonymous with endothermic? If not, how are they different? If so, why are they throwing new terms at me?
