[edit] Article is too complicated

Im at a high level of understanding of Chemistry in my opinion, im studying and understanding AS Chemistry, and I don't understand it. What level is this article aimed at? because to be honest, there won't be many degree graduates reading this! Sorry! Medscin 13:38, 28 January 2006 (UTC)

This is the definition of standard enthalpy change that I learned in high school and again in first quarter freshmen chemistry in college. I don't think this is too complicated. For a basic understanding, readers may use the introductory text, and if they want a mathematical explanation, they can use the general example. However, adding a specific, concrete example may make it more clear. Also, this article should probably be merged with enthalpy, as it is very short by itself. User:carhas0

Merging or redirecting with enthalpy would be a mistake. Enthalpy is a more general term that may refer to chemical reactions, heat transfer, convective flow, and other things besides chemical reactions. I am removing the merge tag. The article right now is a stub and could use expansion and an example to make it better for the general reader, but it shouldn't be merged. Flying Jazz 03:14, 13 February 2006 (UTC)


I'M NOT SURE IF THIS ARTICLE IS CORRECT! The standard enthalpy of reaction does not always involve 1 mole of reactants, it depends upon the reaction equation. It is the standard enthalpy of FORMATION that involves 1 mole. This is according to my OCR A2 textbook! As quoted in the textbook (this obviously does not involve 1 mole of reactants):

                                                         2H2(g)+O2(g) --> 2H2O(l)
                                                                       ΔHθr=-572KJ mol-1
