Analysis:

Conclusion:

I found out that the rate of reaction between calcium carbonate and
hydrochloric acid increases when you increase the temperature of the
hydrochloric acid.

### Hypothesis - Factors Affecting Reaction Rate Lab

2. If the reaction times did not show the expected patterns,can you come up with a hypothesis of what might have gone wrong?Is it possible that practice effectsplayed a role in that you got faster at doing this task with each successivetrial?

Although we don't actually see the workers doing their job, we can inferthat if the store is using large quantities of reactants (dough and toppings)and / or making large numbers of end products (pizzas) that the workers(enzymes) must be very active.

Although you will perform the laboratory exercise working as groups oftwo or three students, make your report an individual effort.

## View Lab Report - Reaction Time lab report from BIOL 110 at Clemson

This benchmark lab is intended for you to explore the reaction time it takes to grasp a meter stick being dropped between fingers. In one trial of 10 drops you will create the control data. In the control data you and your partner will not have any distractions or enhancements while dropping or catching the meter stick. This is your control data, the data you will compare to your experimental results.
