Conclusion (put into lab book - You do not have a 3 paragraph conclusion)

Answer the following questions about Part 1:

1. What is the relationship between the amount of water and the time it takes for the reaction to occur?

2. What does adding water do to the concentration of solution B?

3. How does concentration affect the time it takes for a reaction to occur?

4. Sketch what you think a graph would look like if you were to graph time vs concentration instead of time vs amount of water.

Data (create a data table in your lab notebook that you will use to collect your data for Part 2)

Conclusion (put into lab book - You do not have a 3 paragraph conclusion)

Answer the following questions about Part 2:

5. What is the relationship between the temperature and the time it takes for the reaction to occur?

6. Based on both parts, what are the best conditions of concentration and temperature to speed up a reaction?

Classify the following errors as either human error, experimental error, or no effect on the experiment:

7. Your lab partner does not accurately measure out the ten milliliters of solution A.

8. One group decided to stop the timer when the color first started for every trial and another group decided to stop the timer when the color fully changed for every trial.

9. Due to the nature of the reaction it is hard to determine when the color first starts making it difficult for you to decide when to hit stop on the stop watch.

10. In part 1, the temperature in the room dropped dramatically from trial 1 to trial 6.
