What do you call a reaction that is balanced between forward and reverse processes?

A reaction that is balanced between forward and reverse processes is referred to as dynamic equilibrium. In this state, the rates of the forward and reverse reactions are equal, meaning that the concentration of reactants and products remains constant over time, even though both reactions continue to occur. This concept is crucial in understanding reversible reactions, where the system can shift in response to changes in conditions, such as temperature or pressure.

Dynamic equilibrium is different from static conditions, where there is no movement or change occurring, and from exothermic or catalytic terms that describe specific types of reactions rather than the balance of processes. This balance at equilibrium allows for a constant state in a closed system while still involving ongoing reversible processes. Thus, dynamic equilibrium captures the essential nature of reversible reactions and their behavior within a system.
