Section 9.12 Le Chatelier’s Principle Adding is like pushing Add reactant: R P Add product: R P R P Remove product: Removing is like pulling Remove reactant: R P When a system at equilibrium is placed under a stress, it will respond so as to appear to relieve the stress. http://www.youtube.com/watch?v=f9aTOSpkUng Le Chatelier’s Principle CH 3 I + OH 1- I 1- + CH 3 OH + E Stress: [OH 1- ] What will happen to the [CH 3 OH] when . .. CH 3 I + OH 1- I 1- + CH 3 OH + E CH 3 I decreases I -1 , CH 3 OH, E increase (rxn gets hotter) System reacts to decrease OH -1 As a result: Section 9.12 (exothermic rxn) When a system at equilibrium is placed under a stress, it will respond so as to appear to relieve the stress. Le Chatelier’s Principle CH 3 I + OH 1- I 1- + CH 3 OH + E When a system at equilibrium is placed under a stress, it will respond so as to appear to relieve the stress. Exothermic rxn: think of E as a product Endothermic rxn: think of E as a reactant Stress: T ( i.e., add E) What will happen to the [CH 3 OH] when . .. + E I 1- + CH 3 OH CH 3 I +OH 1- [CH 3 OH] E OH 1- , CH 3 I I 1- , CH 3 OH Reaction Coordinate TS K !
