1. Overall assessment of reactivity. Chemical kinetics or reactions

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 knowledge, the reader can refer to articles already published in Techniques de l'Ingénieur: "Méthodes cinétiques en Chimie analytique" : [P 3 116][P 3 117] , [P 3 118] , [P 3 119] .
