Chemical balance
Chemical equilibrium (English: Chemical equilibrium) refers to the macroeconomic conditions in a certain reversible reaction, the chemical reaction is the same positive and negative reaction rate, the reactants and the concentration of each component does not change the state. Can be judged by ΔrGm = ΣνΑμΑ = 0, μA is the chemical potential of substance A in the reaction. That is, the chemical reaction is in equilibrium, meaning that the Gibbs free energy G of the product is minimized. Theoretically, for the known chemical reactions of the product, the Gibbs minimum free energy method, combined with the thermodynamic data of the reactants and the product, can be used to calculate the equilibrium product. Chemical reactions do not necessarily reach equilibrium, such as the formation of pure products between pure chemical reactants can not be balanced until the reactants consumed. Theoretically, any chemical reaction is a reversible reaction, but only for the chemical reaction with a very large equilibrium constant, the reaction is considered to be irreversible because the reaction is carried out thoroughly. ...
