[edit] Standard state pressure
Putting together the new Template:Chembox I had to research whether standard state pressure is 100 kPa or 101.325 kPa. I found a great deal of confusion, but the later and more "in-depth" literature seems to be unambiguous that it is supposed to be 100 kPa. The 1985 JANAF Thermochemical Tables state that "in all previous tables, the standard-state pressure was 1 atmosphere (101 325 Pa). For this publication, the standard-state pressure is changed to one bar (100 000 Pa)." Yet I found a later (1994) secondary publication, the Concise Encyclopedia of Chemistry (de Guyter) still referring to the older 101 325 Pa standard in their brief entry on standard state. The latest CRC Handbook of Chemistry and Physics unequivocally states that "The standard state pressure is 100 kPa (1 bar)." Their tables are now corrected to this pressure. Therefore I'm going to amend the wording in the article to match this. Walkerma 17:33, 16 May 2005 (UTC)
- What this article should match is basically what you told us here. Not everybody looking for information about "standard state" is going to be looking for information compiled in the last decade. The fact of the change should be clear in the article itself. Gene Nygaard 03:38, 24 August 2005 (UTC)
[edit] Temperature
I received a correction via email that the current IUPAC definition does not include temperature, and this appears to be the case [1], so I have removed that statement. Mindspillage (spill yours?) 20:13, 22 August 2005 (UTC)
[edit] Removal of stubbiness
No one's worked on this page in a year, and it seems to be fairly complete, or at least no longer a stub.--Atemperman 03:55, 25 September 2006 (UTC)
[edit] SI units...
I'm not sure what the convention here on wikipedia is, and don't have time right now (in the middle of chemistry coursework) to find it, but bar is not an SI unit; neither is mol/L for concentration. Perhaps it's just high-school idiocy, but the International Baccalaureate organisation is fairly adamant that temperature is not in the definition, as [User:Mindspillage] said but crucially it is 1 atm rather than 100 kPa. I'll hold off making this last change until someone can provide a good source either way. Simplyw00x 15:54, 4 March 2007 (UTC) Consider reverting to atm. There are 101.3kPa in 1 atm, not 100kPa.
