Reversible reactions

• • Le Chatelier's Principle refers to how if the conditions of a reversible reaction at equilibrium, the system will try to produce the opposite
• • Changing the pressure only affects the equilibrium in gases
  • Increasing the pressure moves the equilibrium in the direction of fewer gas molecules
  • Decreasing the pressure moves the equilibrium in the direction of more gas molecules
• • Using a catalyst does not change equilibrium position, and only helps reach equilibrium quicker
