Exothermic Vs. Endothermic Reaction
Reaction progress diagrams for single-step endothermic andexothermic reactions.
a. Devise a general statement about the relationship between Eaand the rate of a reaction. 

b. Describe the effect of temperature on the energy ofcollisions, and explain how this effect changes the rate of areaction. 

c. State three things that resulted in anincrease in the rate of the reaction. For each of the three things,explain at a molecular level what happens to cause the rate of thereaction to increase.
