Chemical Reactions and Heat Lab

In this lab we got to explore reactants and products. We also got to see how catalysts effect them.

We changed the temperature (catalyst) to see how it effected the time it took to dissolve an alka-seltzer tablet in water.
This table shows the comparison of the experiments depending on the temperature.

  This is the graph for the room temperature test.

  This is the graph for the cold water test.

 This is the graph for the hot water test.

The following diagrams depict our setup and the amount of product produced at an instantaneous time.

Cold = Very few bubbles

Room = Some bubbles

Hot = Lots of bubbles!!!

 What is a catalyst? A catalyst is a particle of matter that changes the rate of reaction. Some xamples of catalysts are temperature and concentration.

 or

 or

alka-seltzer + water =  CO2 bubbles

My hypothesis was that the higher the temperature the faster the reaction would happen. My hypothesis was correct and it was fun to test.

If I were to do this test again I would do all three experiments at once to see if I was physically able to do that many experiments on time and perfectly. It probably won't happen but its a fun idea.
