Effect of Temperature on Rate of Reaction 
 
1. Turn on Hot plate if not already on (turn temp knob to 200-300deg C). 
2. Obtain two 250ml beakers. 
3. From the 400ml containers of 0.10M <nowiki>HCl</nowiki>, add approximately 40ml of this solution to each of the 250ml beakers). (use side of beaker to measure volume 
4. Place one of the two 250ml beaker on the hot plate and let it heat up to some temperature above room temp.(not anywhere near boiling point). 
5. After the beaker comes to temperature, take it off the hot plate. 
6. Measure out the same amount of (about 1/4 teaspoon) sodium bicabonate (Baking soda) and add this amount to each container. Do not mix or stir the solid into solution. 
7. Record your observation after addition (look for rate of bubble formation).
 
Effect of Stirring on Rate of Reaction 
 
1. Now stir the solid and solution for each container (using a coffee stirrer). 
2. Record your observation after each stirring (look for rate of bubble formation). 
 
 
 
Data or Observations
 
 
After adding solid to room temperature solution. 
 
 
After adding solid to above room temperature solution 
 
 
After stirring room temp solution. 
 
 
After stirring above room temp solution 
 
 
Questions: Answer on separate sheet of paper (not in space between questions) 
 
 
1. Would you expect the rate of carbon dioxide formation in the above room temp solution to be greater, equal or less than with the room temp solution? Why? (make sure to use effective collisions in your discussion). 
 
2. Did your observations support your answer in Question 1 (simple yes or no answer) 
 
3. Would you expect the rate of carbon dioxide formation while stirring greater, equal or less than when not stirring the solid in the solution? Why? (make sure to use effective collisions in your discussion). 
 
4. Did your observations support your answer in Question 3 (simple yes or no answer) 
 
5. Have you seen another experiment that would be explained with the same reasoning as in Question 3? You can not use any example of a solid in a solution.
