![]() ![]() ![]() Dynamic equilibriumdoes not necessarily (or usually) occur when equal concentrations of reactantsand products exist in the chemical system. The ideas developed in this activity are: (1) chemicalreactions do not always go to completion, and (2) a state of dynamic equilibriumcan be established in a chemical system by the simultaneous formation ofproducts from reactants and reactants from products.
