ملخص الدرس

This lesson details Le Chatelier's Principle and its systematic application to concentration, pressure/volume, and temperature disturbances. It explains industrial optimization of reversible reactions (e.g., continuous product removal and high pressure in ammonia synthesis). It emphasizes that temperature is the sole factor that changes the numerical value of the equilibrium constant K, while catalysts only accelerate reaching equilibrium.

هتتعلم إيه فى الدرس ده

• Le Chatelier's Principle: A system at equilibrium adjusts to counteract external disturbances.
• Adding reactants or removing products shifts equilibrium forward (right).
• Increasing pressure shifts gas equilibria toward the side with fewer gas moles.
• Heating exothermic reactions shifts left and decreases K; heating endothermic shifts right and increases K.
• Temperature is the ONLY factor that changes the numerical value of K.
• Catalysts accelerate reaching equilibrium without shifting position or altering K.
