Example 1
easyState Le Chatelier's principle and explain what it predicts about equilibrium systems.
Solution
- 1 Le Chatelier's principle states: if a system at equilibrium is subjected to a change (stress), the system will shift to partially counteract that change and establish a new equilibrium.
- 2 Stresses include changes in concentration, pressure, or temperature.
- 3 The system responds by shifting the equilibrium position (favoring either the forward or reverse reaction) to reduce the effect of the disturbance.
Answer
Le Chatelier's principle is a qualitative tool for predicting how an equilibrium system responds to changes. It does not tell us the exact new concentrations, but it tells us the direction of the shift.
About Le Chatelier's Principle
When a system at chemical equilibrium is subjected to an external stress — such as a change in concentration, pressure, or temperature — the equilibrium.
