Test 1 Question 1c

Postby Annie Lieu-1H » Mon Feb 12, 2018 9:51 pm

Hi, for "Do you expect there to be a difference between your answer in part (a) and part (b)? "

I put that there is an expected difference because mean bond enthalpies are more accurate than ΔHf ways. I got the question right but shouldn't it be the other way around because it's a MEAN bond enthalpy, so its an average, and not a real calculation for the particular compound?

Or is the ΔHf one even more average?

No, the bond enthaply method is less accurate because it is an average energy released between the bond between two atoms across a multitude of molecules.

Bond enthalpies are the least accurate way to calculate enthalpy of formation because they are averages

My bad, misread my own handwriting.
