This question was created from Student Handout - Reaction Rates.doc


2. You have learned that temperature, concentration and activation energy WIII change the rate or a
reaction. Complete the table below by comparing your predictions to your observations.
a. Predict what will happen to the rate of the reaction for each variable listed below.
b. M your prediction with the simulation and record observations.
c. Explain your observations. Were all of your predictions correct? Which tests changed
your thinking about reaction rates? How did the simulation change your prediction? “mm Will move faster It moved faster More energy Increase
temperature Will move slower It moved slower Less energy Decrease
temperature Molecules will hit each other It had a faster rate of The increase in
more often reaction concentration increases Increase '
the art of reaction concentration of the
reactants Will not hit each other as It had a slower rate of The decrease in
Decrease often reaction concentration decreased
concentration of the the rate of reaction. reactants 3. Review your observations from questions #1 & 2. Write a summary paragraph, which includes
drawings, which demonstrate you have mastered the learning goal.
