Rate of Reaction - Clock Lab with Temp Change
Chemical Reactions
Effect of temperature on rate of reaction:
Directions(Procedures)
1. Add 5mL of Solution A and 5ml of water into a 100mL beaker (Label A/water).
2. Add 10mL of Solution B into another 100mL beaker (Label B).
3. Place both 100mL beakers into the "cold water" bath and let solution get to temperature for 3-5mins.
4. Once at temperature, pour Solution A/water into reaction beaker (another 100mL beaker) and then Solution B.
5. Start recording time when Solution B is added to reaction beaker (i.e. Solution A/water).
6. When you "see change", record the time it took to get there, as Lower (cold) temp:.
7. Repeat the same procedures (1-6) but just with the hot water bath. Record as Higher (Warmer) Temp.
