Answers the following questions in the space provided. 
 
1. Write the chemical reaction for the Hydrogen Peroxide lab including phase (assume it NOT a reversible reaction). 
 
 
2a. What is the chemical name and chemical formula of the catalyst used in Hydrogen Peroxide lab. 
 
2b. Besides influencing the rate of the reaction (and how it is done), the other major attribute of a catalyst is. 
 
 
4a. For the ________________ (look at front board) lab, what was the physical observation that determine the rate of reaction. 
 
 
4b. For the _____________________(see front board) lab, was the numeric values of the physical observation and the rate of reaction (i.e. how fast you made product), directly proportional or indirect/inversely proportional to each other (i.e. as one number went up, other number went up would be directly proportional). Explain your answer. 
 
 
 
 
5. On the back of this page, explain) how increasing________________(see front board for stress) will increase the rate of reaction (from either lab). Please make sure you show the Kinetic Energy Diagram and how the graph helps to explain why there is an increase in the rate of reaction. Graphs don't say anything you must show the graph then explain what the graph means.
