Gibbs Free Energy - Purdue University Reactions can also be classified as exergonic (G < 0) or endergonic (G > 0) on the basis of whether the free energy of the system decreases or increases during the reaction. When a reaction is favored by both enthalpy ( H o < 0) and entropy ( S o > 0), there is no need to calculate the value of G o to decide whether the reaction should proceed . 4 Energy and Rates of Chemical Reactions After you read this section, you should be able to answer these questions: • How is energy involved in a chemical reaction? • What are exothermic and ... 6 • Energy and Chemical Reactions - chemmybear.com South Pasadena • AP Chemistry.
