Key concepts

3 concepts

  1. 1

    Le Chatelier's principle states that a system at equilibrium will shift to relieve stress induced upon it.

  2. 2

    Stresses on a system can include changes in concentration, temperature, or volume/pressure.

  3. 3

    For reactions involving gases, decreasing the volume will increase the pressure, causing the equilibrium to shift towards the side with fewer particles.

12 questions

1

State Le Chatelier's principle in your own words.

2

For the reversible reaction N₂(g) + 3H₂(g) ⇌ 2NH₃(g), predict the shift in equilibrium if more N₂ is added to the system.

Part 4 of 4

Exit ticket

Quick comprehension check

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.
