Are there any periodic trends for enthalpy?

Postby Ishan Saha 1L » Fri Jan 12, 2018 4:18 pm

I was just wondering if there was any trend for bond enthalpy? Does it correspond to bond strength or ionization energy or anything like that?

No, I don't think so

Even if there are, I don't think you need to worry about them :)

There are trends for bond enthalpies, in the sense that if there are generally more molecules, for instance NO vs NO3, NO3 will have a higher bond enthalpies to account for the additional oxygen molecules that are attached to the Nitrogen. Otherwise I don't think so.

To add on to the previous posts, professor Lavelle said we do not need to memorize bond enthalpies, so we most likely do not need to know them if there are any. I do think that it may correspond to bond strength, because bond enthalpy is the energy needed to break a bond.
