Subject field(s)
  • Chemistry
DEF

An expression that gives the rate of a reaction as a function of concentrations; often called the rate law.

CONT

The differential rate law describes how the rate of reaction varies with the concentrations of various species, usually reactants, in the system. The rate of reaction is proportional to the rates of change in concentrations of the reactants and products; that is, the rate is proportional to a derivative of a concentration.

OBS

There are two forms of a rate law for chemical kinetics: the differential rate law and the integrated rate law.

CONT

Équation de vitesse intégrée. Jusqu'à présent les équations de vitesse utilisées ne permettaient d'exprimer que la variation de vitesse en fonction de la concentration des réactifs. Il est aussi utile d'exprimer la variation de concentration des réactifs en fonction du temps, une fois que l'on connaît l'équation de vitesse différentielle.

CONT

Lois de vitesse : formes différentielle et intégrale.
