Le Chatelier's Principle
Guided Notes
3 key concepts
- 1
Le Chatelier's principle states that a system at equilibrium will shift to relieve stress induced upon it.
- 2
Stresses on a system can include changes in concentration, temperature, or volume/pressure.
- 3
For reactions involving gases, decreasing the volume will increase the pressure, causing the equilibrium to shift towards the side with fewer particles.

“Consider the following reaction at equilibrium: N₂(g) + 3H₂(g) ⇌ 2NH₃(g) + heat. Predict the shift in equilibrium (left, right, or no change) if: (a) the concentration of N₂ is increased, (b) the temperature is decreased, and (c) the pressure is increased.”
