Detailed balance is a thermodynamic concept that refers to a state where the forward and backward reactions of a chemical or physical process occur at equal rates. It is also known as the principle of microscopic reversibility. Synonyms for detailed balance include detailed equilibrium, micro-reversibility, and microscopic time-reversal symmetry. These terms are used interchangeably across various fields such as chemistry, physics, and biology. Additionally, notions such as equilibrium thermodynamics, chemical equilibrium, and balance conditions are also relevant to the concept of detailed balance. Understanding the principles of detailed balance and its synonyms is essential for scientists in a variety of fields, as it is a core principle underlying many natural processes and physical phenomena.
