Abstract
Based on the general theory of chemical kinetics, a theoretical model was developed for the formation and dissociation of a gas hydrate. An expression is derived for the driving force of the formation and dissociation. The presented theory was compared with other well-known theoretical models and, from the available experimental data, the temperature dependence was determined for the methane hydrate formation and dissociation rate constants.
