Changes

A typical [[chemical]] usually results in an '''equilibrium''' system. Called a dynamic equilibrium, this is when the rate of change of the forward and reverse reactions occurs at the same rate. <ref> Ebbing, Darrell D. and Steven D. Gammon. ''General Chemistry: Eighth Edition''. New York: Houghton Mifflin Company, 2005.</ref> In other words, the ratio of reactants and products remains the same.

An equilibrium occurs because most reactions do not go to completion. (A reaction can only go to completion if the product is continually being removed from the system.)
