Measuring Rates
... The integrated rate law for a chemical reaction expresses how the concentration of a relevant reacting species changes as a function of time. Thus, it can be used to predict the time it will take for a reactant or product to reach a given concentration, or to predict such concentration at a selected ...

Chemical equilibrium
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time. Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction. The reaction rates of the forward and backward reactions are generally not zero, but equal. Thus, there are no net changes in the concentrations of the reactant(s) and product(s). Such a state is known as dynamic equilibrium.
