Question

For this activity we're going to utilize a simulation lab to make observations and 'graph' data. Simulation: Investigating Reaction Rates will be the activity that will help you. When you click the link, you may need to scroll your page down just a smidge for the best view. It should open in a separate window for you to continue to work from here.

When you open the simulation you should see a beaker that is holding a solution containing reactants 'A' and 'B'. They will react to form product 'C'. [Blue + Red → Purple]

For your first question, please just let me know which choice best describes the role of a "control group" in an experiment.
