Study Notes
Le Châtelier's Principle
- The primary objective of Le Châtelier's principle is to describe how a system at equilibrium responds to changes in concentration, temperature, or pressure.
Sabatier Process
- In the Sabatier process, adjusting the concentrations of reactants or products, temperature, or pressure allows the system to reach a new equilibrium state.
- The primary function of methane (CH4) in the Sabatier process is to react with hydrogen to produce methanol.
- The reaction is conducted at a high temperature, typically around 300-400°C.
Test your understanding of Le Châtelier's Principle and its application in predicting the effects of changes in concentration, volume, pressure, and temperature on chemical equilibrium in closed systems. This quiz will help you assess your knowledge of factors affecting chemical equilibrium in Grade 12A Chemistry.
