1. Rates and Equilibria
Chemistry Unit 5

2. Iodine clock reaction We think… Our Questions
All the flasks turned the same color (dark purple/brown)
The reactions had different times (A was fastest, E was slowest)
If we increase the percent H2O2 the reaction will go faster
Some flasks reacted faster because they were more concentrated
What was in the beaker?
Why did the color change?
How does E have less H2O2 than A?
Can this happen with a different reaction?
What would happen if we added more iodine?
Why does the amount of H2O2 change the time?
Can it change a different color?
How did reaction A happen so fast?
What makes it react?
How do they bond?
Was it the same reaction every time?
How is stuff this used in real life?

3. Question 1: What makes it react?
What really happens during a chemical reaction?
How do atoms interact with each other?
