Unformatted text preview: Monday, October 23, 2006 Chemistry EQUILIBRIUM Part 1 Whats a reversible reaction? Where does it finish? Can we change where it finishes? Text: Sections 9.11 (part) 9.12 REVERSIBLE PROCESSES 1. Freeze H 2 O vs. Fry egg 2. Reversible a. Products can go back to reactants Spontaneity is not absolute 3. Write with double arrows CH 3 I + OH 1- CH 3 OH + I 1- REACTIONS AT EQUILIBRIUM 1. When reversible reactions reach equilibrium (when they are at equilibrium) Rate foward = Rate reverse dynamic equilibrium. Both reactions still going Amounts of reaction and products no longer changing 2. Equilibrium constant (K) a. Gives product/reactants ratio at equilibrium [Products] power K = Coefficient in Balanced Equation Concentration of [Reactants] power use concentration for gases & species in solution use 1 for liquids & solids Expression for K comes from balanced equation CH 3 I + OH 1- CH 3 OH + I 1- Monday, October 23, 2006 [CH 3 OH] [I 1-...
