Le Ch â telier’s Principle

Le Ch â telier’s Principle . The Principle. When a chemical system at equilibrium is disturbed by a change in a property, the system adjusts in a way that opposes the change! [CoCl 4 ] 2- ( aq ) + 6H 2 0 ⇌ [Co(H 2 O) 6 ] 2+ + 4Cl - + Heat Left side: blue, right side: pink.

Presentation Transcript

  1. Le Châtelier’s Principle

  2. The Principle • When a chemical system at equilibrium is disturbed by a change in a property, the system adjusts in a way that opposes the change! • [CoCl4]2-(aq) + 6H20 ⇌ [Co(H2O)6]2+ + 4Cl- + Heat • Left side: blue, right side: pink

  3. Summary

  4. Reaction Game! In your groups, decide whether the equilibrium shifts left or right!

  5. Concentration CCl4 + 2 HF ⇌ CCl2F2 + 2HCl • Remove some HF • Add some drops of HCl • Add CCl4 • Remove CCl2F2

  6. Temperature AND Concentration CH4 + 2O2 ⇌ 2H2O + CO2 • Removing heat • Syphoning out CO2 • Doing the reaction in an area with little oxygen • Doing the reaction in a sauna

  7. PRACTICE p. 457 #1,4-8(a,b)
