First-Year University Chemistry Textbooks' Misrepresentation of Gibbs Energy
Quilez, Juan
Journal of Chemical Education, v89 n1 p87-93 Jan 2012
This study analyzes the misrepresentation of Gibbs energy by college chemistry textbooks. The article reports the way first-year university chemistry textbooks handle the concepts of spontaneity and equilibrium. Problems with terminology are found; confusion arises in the meaning given to [delta]G, [delta][subscript r]G, [delta]G[degrees], and [delta][subscript r]G[degrees], which results in many textbooks not differentiating between [delta]G and [delta][subscript r]G. Also, there is confusion over when standard conditions apply and when they do not. A problem with the proper use of units is also found. Finally, it is suggested that most of these difficult concepts could be removed from the first-year university chemistry syllabus because (i) an accurate presentation of Gibbs energy would be far beyond an introductory chemistry level and (ii) current attempts to introduce those difficult concepts in first-year university chemistry courses are usually full of misleading formulations. (Contains 4 tables and 1 figure.)
