3 methods

Postby Alexis Robles 2k » Sun Jan 26, 2020 10:13 pm

From the three methods, why should we use a certain method over the others? Thanks

You should use certain methods based on the information you are given, so different methods for different circumstances, but also I believe that the methods using bond enthalpies is the least accurate method because the bond enthalpies of non-diatomic molecules are averages from many different molecules.

I think it would depend on what information the problem gives you. However, I believe the standard enthalpy of formation is more accurate than using bond enthalpies.

It would depend on the information the question gives you. It also depends on what you are looking for. If you are looking for an accurate enthalpy, you should avoid using bond enthalpies because it is the least accurate.

What would be an example of a question where you would use Hess law to answer?

Depends on given info but bond enthalpies method least accurate
