Title: Heat of Formation Tables
Post by: ifuller on January 02, 2008, 10:38:00 PM

Hello,
I am looking for a very complete deltaH table. I have googled this but am coming up short. I need one more complete than one found on say wikipedia or something like that. Any suggestions would be greatly appreciated. Thanks

CRC Handbook of Chemistry, or Lange's Handbook of Chemistry, etc.

Freely available at your local library, and possibly available online at home through your schools library system using your library id #.

Those are the best...but this one comes in handy...it is called The Table of Tables.  Scroll down...3rd option down...pretty complete...not like those two book though..

Isn't it paid access and of no use to most of the users?

First of all   MY BAD:  try this link:  http://hyperphysics.phy-astr.gsu.edu/hbase/tables/ttab.html

If you belong to a HS or University....usually your library has an account...same with industry CRC is usually provided....

One more question. I have found a copy of the Handbook of Chemistry and Physics that has a table of the heats of formations. I have also found a website with a pretty complete table here:
http://www.update.uu.se/~jolkkonen/pdf/CRC_TD.pdf
The problem is the book shows some of the heats as being positive that the table shows are negative and vis versa. Any suggestions to help clear this up. Thanks
