Unit 5 Connexus Portfolio:  Investigate the Concentration vs. Reaction Rate

Part 1: (total 4pts)

1.  What is collision theory?
2. How does changing concentration affect collision theory and reaction rate?

Part 2 (total 12pts)

1.  What are the variables?  (3pts)
   1. Independent variable (what you change in the experiment):
   1. Dependent variable (the outcome that you observe or measure):
   1. Constant (what keep the same throughout the experiment):
2. Material list (1pt)
3. Procedure (clear and appropriate to the task and purpose-logical steps) (4pts)
4. Data table (table is clear, organize and appropriate data were recorded) (4pts)

Part 3 (total 8pts)

1. Analysis (Interpret the data –how does it fit with the collision theory and rate of reaction? Evidence to support the interpretation) (4pts) 
2. Graph and Interpret the graph (4pts) (You can use computer to graph and insert the graph here, or graph by hand but make sure you use ruler)
