Thermochemistry was a new unit we started! I learned about endothermic and exothermic reactions. Catalysts speed up a reaction, but don't get consumed in it. Activiation energy is reduced because of those also.
The graph for exothermic and endothermic reactions are opposite. Energy can't be lost or gained so it is EVERYWHERE! The packet took a long time to do, but I still got full points on it, so I'm proud of myself. I think I did pretty good on the test too! There were a lot of equations like the changing phases one which included a combination of many of them. It was a very confusing unit, but still oh so interesting.
