WebJun 8, 2024 · In an exergonic chemical reaction where energy is released, entropy increases because the final products have less energy inside them holding their chemical bonds together. That energy has been lost to the environment, usually in the form of heat. All physical systems can be thought of in this way. WebB. Forming a peptide bond increases the entropy of a system C. Forming a peptide bond is spontaneous and does not need to be coupled to another reaction D. Forming a peptide bond is exergonic and must be coupled to another reaction E.
