20 Ιουλ 2023 · Equilibrium constants can be used to calculate the equilibrium concentrations of reactants and products by using the quantities or concentrations of the reactants, the stoichiometry of the balanced chemical equation for the reaction, and a tabular format to obtain the final concentrations of all species at equilibrium.

In a chemical reaction, chemical equilibrium is the state in which both the reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system. [1]
13 Νοε 2022 · Chemical equilibrium. When a chemical reaction takes place in a container which prevents the entry or escape of any of the substances involved in the reaction, the quantities of these components change as some are consumed and others are formed.
Chemical equilibrium is the condition of a system where the concentrations of the reactants and products do not change with time. Also, the system does not show any change in its properties. During a reversible reaction, when the forward and reverse reaction rates become equal, the system achieves the state of chemical equilibrium.
14 Αυγ 2020 · For a system at equilibrium, the law of mass action relates \(K\) to the ratio of the equilibrium concentrations of the products to the concentrations of the reactants raised to their respective powers to match the coefficients in the equilibrium equation. The ratio is called the equilibrium constant expression.
At equilibrium, Q = K. a, b, c, d are coefficients in balanced eqn. (Qc means Q expressed in [ ]’s). At equilibrium, Qc = Kc. check: not balanced, so we must balance it first! Note: (i) Q and K are unitless numbers, because each conc is divided by standard conc = 1.00 M, so the units (M) cancel.
Chemical equilibrium occurs when a reaction and its reverse reaction proceed at the same rate. In the figure above, equilibrium is finally reached in the third picture. As a system approaches equilibrium, both the forward and reverse reactions are occurring.
