Overall assessment of reactivity. Chemical kinetics or reactions
Réactivité des molécules organiques et stabilité

Chemical kinetics play an important role in product stability studies, as well as in biopharmaceutical and drug metabolism studies. Indeed, a thermodynamically favored reaction cannot take place if its rate is infinitely slow, except in the presence of a catalyst likely to accelerate it. The contribution of chemical kinetics will not be developed here; for a more in-depth understanding, readers may refer to articles already published in Techniques de l'Ingénieur. .

The accelerated study of product stability is based on the application of the fundamental theories and principles of physical chemistry and chemical kinetics. In solution, the speed v of a reaction is a function of the number of collisions between the product under study M and the solvent molecules W :
