Chemical reaction

“The simplest chemical reactions may be described as equilibration between two distinct species. Such processes are governed by two fundamental considerations: 1. Chemical thermodynamics, … 2. Chemical kinetics, ...”

“In many cases, equilibrium lies extensively (say, more than 99.9%) on the side of the products. When this occurs, the reaction is said to go to completion.”

“All reactions are described by equilibrating the concentrations of starting materials and products. On which side the equilibrium lies depends on the size of the equilibrium constant, which in turn is related to the Gibbs free energy changes ...”
