In the course of a first-order reaction, the half-time t1/2 is the time required for one-half of the initial reactant to be consumed. ... In first-order reactions the half-time is independent of the initial concentration of substrate. 3, record 1, English, - first%2Dorder%20reaction

Réaction dont la vitesse est exactement proportionnelle à la concentration d'un réactif. Soit une réaction fort simple dans laquelle une substance A se transforme en substance B. A tout instant chaque molécule A a une égale probabilité de subir la transformation, la vitesse globale de la réaction dépend donc de la concentration de A. 2, record 1, French, - r%C3%A9action%20du%20premier%20ordre

Les réactions d'ordre un jouent un grand rôle dans les phénomènes physiques et biologiques. [...] Ainsi la désintégration radioactive répond à une cinétique de premier ordre, la croissance bactérienne est également un phénomène exponentiel. 4, record 1, French, - r%C3%A9action%20du%20premier%20ordre

ordre d'une réaction: Nombre de réactifs dont la concentration s'altère. Il est donné par l'équation différentielle de Van't Hoff [dx/dt = K.Cn] où le premier nombre représente la vitesse de réaction et C la concentration. Si n = 1, la réaction est du premier ordre. 3, record 2, French, - r%C3%A9action%20du%20premier%20ordre
