WebA reaction is reversible or irreversible depending on the conditions in which this reaction occurs. If there's a sustained high concentration of substrates, most of the reaction flux … In science, a process that is not reversible is called irreversible. This concept arises frequently in thermodynamics. All complex natural processes are irreversible, although a phase transition at the coexistence temperature (e.g. melting of ice cubes in water) is well approximated as reversible. In thermodynamics, … See more Thermodynamics defines the statistical behaviour of large numbers of entities, whose exact behavior is given by more specific laws.
