Today, in class, I learned about the two reactions. I know connecting bond releases energy, and breaking it requires and aborb/ consumes energy. But on my reference table I, 2C+H2 yielding C2H2 realeasing 227.4 kJ of energy. My point is why it releases energy? Also, where the activation energy comes from?
The paradox exists in that lower energy level means more stability, but nature also likes to form bonds thus to increase stability. However, sometimes forming bonds increases the energy level.
