Which term refers to a state of balance?

The term that refers to a state of balance is "equilibrium." In various contexts, equilibrium can denote a condition in which all forces acting on a system are balanced, leading to a state of stability. For example, in physics, it describes when opposing forces are equal, resulting in no net change in motion. In chemistry, it can refer to a state where the rates of the forward and reverse reactions are equal, leading to a stable concentration of reactants and products. This concept is also applicable in economics to describe market conditions where supply and demand are balanced.

The other terms do not relate to balance in the same way. "Erroneous" refers to something that is incorrect or mistaken, "eradicate" means to completely eliminate, and "engrossing" describes something that is extremely interesting or absorbing. None of these words conveys the idea of balance as effectively as equilibrium does.
