Pre-Lab Complete this pre-lab exercise, rather than the one provided in your lab book. 1. Write sentence explanation of the collision theory of chemical reactions using your own words. Use the term reactant in your explanation. 2. Using the collision theory of chemical reactions, describe why each of the following factors can influence the rate of a chemical reaction. a. quantity or concentration of reactants: b. temperature: presence of a catalyst c. 3. Outline, using numbered steps, how you measure the reaction rate of some chemical reaction. 4. If the initial concentration of a reactant was 0.015 moles/liter, and all the reactants turned into products in 23 seconds, what is the (average) rate of the reaction?
