Formalization of the kinetics for autocatalytic dissolutions. Focus on the dissolution of uranium dioxide in nitric medium
Uranium dioxide dissolution in nitric acid is a complex reaction.On the one hand, the dissolution produces nitrous oxides (NOX), which makes it a triphasic reaction.On Storage Table the other hand, one of the products accelerates the kinetic rate; the reaction is hence called autocatalytic.The kinetics for these kinds of reactions need to be formal
