Clock Lab - Concentration Change ([Rate of Reaction - Clock Lab Concentration change])
1. For this lab, what is the physical observation that determines rate of reaction?
2. Explain how this physical observation relates to the products make? Is it a direct (or indirect) proportion?
3. What were the results of the experiment? Did the results support what you learned in lecture about the effect of increase reactant concentration on rate of chemical reactions. (Answer in a sentence, not just "yes" or "no")?
4. Using the Kinetic Energy Diagram (and if needed lecture notes), explain why the experiment results supported or does not support your understanding of changes in reaction rate due to reactant concentrations.
Clock Lab - Temperature Change (Rate of Reaction - Clock Lab with Temp Change)
1) Same question(s) as Question 3 except you are using change of temperature data.
2) Same question(s) as Question 4 except you are using change of temperature data.
3) After "actually doing this section of the lab", is there any changes to the lab procedures that you think would provide more accurate/precise and/or ease of data collection? (Answer with a sentence not just "yes" or "no").
