Bond Enthalpy w/ Diagram

Postby Salma Sudarmadji 2I » Sun Feb 12, 2017 8:07 pm

In a complex diagram of a reaction, how can you tell which bonds are broken and which are formed?

bonds in reactants are broken and bonds in products are formed; count the different types of bonds in both the reactants and products, and if they show up on both sides then you don't have to account for them because they cancel out.

But when we calculate the change in Bond enthalpy, we have to know which specific bonds are broken and which are not broken. That being said, I agree with the difficulty in determining which ones actually break and which ones are the same. I get messed u on counting them that way.
