Clock Lab (Concentration of Reactant vs. Reaction Rate)
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 (inverse) 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. Explain.
4. With increasing concentration of reactant, the rate of reaction _____________________ . Explain (how do we say it in lecture notes).
Hydrogen Peroxide Lab (Temperature vs. Reaction Rate)
1. For this lab, what is the physical observation that determine rate of reaction.
2. What are the results of the experiment and explain how it does or does not support the trend ( T vs. rate) stated in your lecture notes.
3. With increasing temperature, the rate of reaction _____________________ . Explain (how do we say it in lecture notes).
Hydrogen Peroxide Lab (Presence of Catalysts vs. Reaction Rate)
1. What is name of the catalyst?
2. What are the results of the experiment and explain how it does or does not support the trend ( T vs. rate) stated in your lecture notes.
3. With presence of a catlyst, the rate of reaction _____________________ . Explain (how do we say it in lecture notes).
Lycopodium (Increased surface area vs. Rate of reaction)
1. What is name of the reactants and name of chemical reaction? Write the chemical reaction below (not balanced)
2. What product did you use as a physical observation of the rate of the reaction.
3. What are the results of the experiment and explain how it does or does not support the trend ( Catalyst vs. rate) stated in your lecture notes.
3. With presence of a catlyst, the rate of reaction _____________________ . Explain (how do we say it in lecture notes).
4. Can you think of any food product that could produce "dust" and maybe possible to ignite, explain?
