Le Châtelier's Principle Applications

⚖️ Le Châtelier's Principle Rescue Plan

📐 Key Concept: If a stress is applied to a system at equilibrium, the system shifts to minimize that stress.

🔁 Add → Shift away. Remove → Shift toward. Think balance. Think pressure.

🔥 Common Stress Scenarios

• Adding or removing a reactant/product
• Changing the temperature (depends on exo/endothermic)
• Changing pressure (only affects gases)
• Adding an inert gas = no shift!

🧠 Quick Challenge

In the equilibrium: N₂ + 3 H₂ ⇌ 2 NH₃, what happens if H₂ is removed?

⚡ Exam Hack:

When temp changes, think of heat as a reactant (endothermic) or product (exothermic). Add heat = shift away!

📊 Real Exam Style

In an endothermic reaction, what happens if temperature is increased?

✏️ Tip: Add = Away. Remove = Toward. Temp? Treat heat like a substance!
