Get into it! During gas hydrate formation, competition of kinetic preference and thermodynamic stability determines the structure. Kinetically favored sII transformed to thermodynamically favored sI and sH phases. The sH phase is kinetically preferred over the sI phase because of the existence of large cages that can be filled with guest molecules.
