📌 Key Facts: Equilibrium

  • Dynamic equilibrium: Forward rate = backward rate in a closed system
  • Le Chatelier's Principle: System shifts to oppose any change
  • Temperature ↑: Shifts in endothermic direction (absorbs heat)
  • Concentration ↑: Shifts away from the increased substance
  • Pressure ↑: Shifts to side with fewer gas molecules
  • Catalysts: Speed up both directions equally, no position change
  • Concentrations constant but not necessarily equal at equilibrium
