Catalysis by a bifunctional chemical species involving a mechanism in which both functional groups are implicated in the rate-limiting step, so that the corresponding catalytic coefficient is larger than that expected for catalysis by chemical species containing only one of these functional groups.

French

Domaine(s)
  • Génie chimique
DEF

Catalyse par une espèce chimique bifonctionnelle selon un mécanisme supposant l'intervention de deux groupes fonctionnels au cours de l'étape cinétiquement limitante. Il en résulte que le coefficient catalytique est supérieur à celui attendu si la catalyse ne faisait intervenir que des espèces ne possédant que l'un de ces groupes fonctionnels.

OBS

Cette expression ne doit pas être utilisée pour désigner l'action concertée de deux catalyseurs différents («catalyse concertée»).
