Definition of chemical equilibrium
The establishment of chemical equilibrium is premised on the reversible reaction. Reversible reactions refer to the same article
The reaction can be carried out both forward and reverse. Most chemical reactions are reversible and can be balanced to varying degrees. Chemical equilibrium refers to the state in which the forward and reverse reaction rates of a chemical reaction are equal in a reversible reaction with certain macroscopic conditions, and the concentration of each component of the reactant and product no longer changes. It can be judged by ΔrGm = ΣνΑμΑ = 0, μA is the chemical potential of substance A in the reaction. According to the Gibbs free energy criterion, when ΔrGm = 0, the reaction reaches the maximum and is in equilibrium.
