I just finished up my first class of chemistry, and have a question on something that I just can't figure out. The delta H of formation for diatomic molecules is 0. I just don't understand why this is. If there is a reaction, and O2 is one of the products, why is there no heat released when O2 forms? Doesn't each molecule of Oxygen go from a higher energy state to a lower energy state when O2 forms? Thanks in advance for any help.
