Using Method 2

Postby Petrina Kan 2I » Sun Jan 26, 2020 6:28 pm

Since method 2 is the most inaccurate method, when should we ever use it? It seems as though this is the most complicated a time consuming method with the bond enthalpies, so would there ever be a case where we should use this method as opposed to methods 1 or 3?

i think the method you use just depends on the information you are given and since bond enthalpy values are usually something you can look up/ would be given, you could use this method if you are not given the information for Hess's Law.

i believe that sometimes we will only be given the individual bond lengths and will have to use method 2.
