WebApr 11, 2024 · Chemical reactions can be either exothermic or endothermic. Exothermic reactions release energy, while endothermic reactions absorb energy. This energy can … WebThe change in free energy of a reaction can be negative (releases energy, exergonic) or positive (consumes energy, endergonic). All reactions require an initial input of energy to proceed, called the activation energy. Enzymes are chemical catalysts that speed up chemical reactions by lowering their activation energy.
WebSep 16, 2024 · Most chemical reactions can be classified into one or more of five basic types: acid–base reactions, exchange reactions, condensation reactions (and the reverse, cleavage reactions), and oxidation–reduction reactions. The general forms of these five kinds of reactions are summarized in Table 7.10.1, along with examples of each. WebThis small amount of energy input necessary for all chemical reactions to occur is called the activation energy (or free energy of activation) and is abbreviated E A (Figure 6.10). Why would an energy-releasing, negative ∆G reaction actually require some energy to proceed? The reason lies in the steps that take place during a chemical reaction.
