Question: How does temperature affect the rate of a reaction?

Hypothesis: The higher the temperature, the faster the particles. The lower, the slower.


Materials
Two cups or jars
Antacid tablets
Thermometer (if you have one)
Timing device

Procedure
Fill cup one with room temperature water, cup 2 with hot water, and cup 3 with ice water. You can take the temperature of the water if you have a thermometer.
Add one tablet to each cup and record how long it took for the antacid tablet to dissolve.
Repeat experiment two more times. Try to use the same temperature water each time.
