WebOutils. Une réaction chimique contrôlée par la diffusion (ou limitée par la diffusion) est une réaction qui est tellement rapide que sa vitesse de réaction est égale au taux de transport des réactifs à travers le milieu réactionnel, le plus souvent une solution liquide 1. Aussitôt que les réactifs se rencontrent, ils réagissent. WebJan 26, 2024 · Kd is dissociation constant. which describe how affinite two reactants are in a reaction. The following reaction is an example to show dissociation constant: k 1 A + B ↔ AB k -1 Where A and B are the two reactant, AB is the formed complex, k -1 is the reverse constant rate, and k 1 is the forward constant rate.
