CINÉTICA QUÍMICA Informe # 4
Nombre: Analía Rodríguez Díaz
Profesor: Ing. Juan José Álava
1. Objetivo General
Analizar el efecto de la concentración de un determinado reactivo sobre la velocidad de
reacción para el estudio de la cinética química mediante simulaciones.
2. Objetivos Específicos
2.1. Encontrar la influencia que tiene la constante de velocidad (k) en las ecuaciones de
reacción para el orden 0,1 y 2 para la interpretación de sus gráficas.
2.2. Determinar el orden de la reacción mediante el uso del coeficiente de determinación
R2 y las gráficas de orden 0,1 y 2.
3. Datos recopilados
Observaciones • Cambios de color en las muestras como un indicio del término de la
generales del reacción.
