Gibbs' equation., Critical phenomena (Physics), Chemical kinetics., Phase rule and equilibrium.


The critical phenomena that is exhibited in single component systems such as the ferromagnet and the pure fluid have been shown to have analogs in certain multicomponent, chemically reacting mixtures. These phenomena present in both equilibrium and kinetics. By employing a version of the Gibbs phase rule that has been modified to account for chemical reactions, we provide a basis for classifying the critical effects observed in these multicomponent systems. We also show the predictive power of this classification system by comparison with experimental results.
