Endergonic vs. Exergonic Reactions: Understanding Energy Changes in Chemical Processes In the fascinating world of chemistry, energy plays a central role in determining whether a chemical reaction will occur spontaneously or require external input. Two key concepts—endergonic and exergonic reactions—help define the energy dynamics of these processes. Understanding the differences between endergonic and exergonic reactions is essential for students, chemists, and anyone exploring the principles of thermodynamics and biochemistry. ### What Are Chemical Reactions in Terms of Energy? Chemical reactions involve the breaking and forming of chemical bonds, processes that require or release energy. The overall energy change can be measured as a function of Gibbs free energy (ΔG), which indicates whether a reaction is energetically favorable or unfavorable under constant temperature and pressure.
