Understanding Gibbs Free Energy change. Identifying reactions that are thermodynamically spontaneous.
The attached problem file shows the standard Gibbs Free Energy Change for two reactions. Considering these values, which reaction is more favoured or spontaneous?
A reaction with a delta Go = 16 kcal mole-1?
Or a reaction with a delta Go = -16 kcal mole-1?
The solution provides a description of one of the key concepts of introductory chemistry and/or thermodynamics: how to determine whether a chemical reaction will proceed spontaneously. (Nomenclature hint: Spontaneous reactions are also called "favoured of favored reactions".) After studying this solution, the student should have a solid understanding of how to approach this very typical exam-type question.
