1. WED, MARCH 31, 2010 Learning Goal – to prepare for test over rates and equilibrium Questions over the Equilibrium and ICE wkst What to expect on test Time to work and ask questions Homework

2. ANSWERS TO EQUILIBRIUM AND ICE WORKSHEET 1. A. Equilibrium problem K eq = 0.018 B. Equilibrium problem; K eq = 0.050 or 0.049 2. ICE problem; K eq = 0.0028 3. A. Equilibrium problem; K eq = 0.659 B. ICE problem; K eq = 0.18 4. A. Equilibrium problem; K eq = 0.0266 B. Equilibrium problem; [NH3] = 0.155M Any Questions?

3. WHAT TO EXPECT ON THE TEST 10 Multiple Choice 5 problems (most have a Part A, B, and sometimes C to them) Energy Diagram (graph) to interpret Collision Theory (rate of reaction) Factors that affect rate, and factors that affect equilibrium Know vocab from the review K eq and ICE problems – are reactants or products favored based on K eq value Rate Calculations (from Something to Zn About Lab) LeChatelier Questions – which way will reaction shift, what will happen to concentrations after the shift, etc.

4. HOMEWORK: Finish Ch 19 Review – will turn in on Friday Finish Equilibrium problems packet – will turn in Friday Bring Something to Zn About Labs Friday Something to Zn About Moodle Quiz – closes Mon Study for test – Friday! Study your in-class notes, study guide, etc
