EQUILIBRIO QUÍMICO Informe # 5
Nombre: Analía Paulina Rodríguez Díaz
Profesor: Ing. Juan José Álava
1. Objetivo General
Analizar el efecto de la concentración de un determinado reactivo sobre la variación del
equilibrio químico de un sistema para el estudio de esta perturbación.
2. Objetivos Específicos
2.1 Determinar la influencia de la temperatura en las concentraciones de los productos
para el estudio de la constante de equilibrio (K).
2.2 Describir los factores que perturban el equilibrio químico a través del Principio de
Le-Chatelier.
3. Datos recopilados
• Los valores de las concentraciones del producto son subjetivos
debido a qué tanto se acercó al color de las muestras dentro del tubo.
Observaciones
• Se observa una tendencia con respecto a los volúmenes en ml del
reactivo SCN- y el de agua.
