Question

5. A catalyst is a substance used to increase the rate of a chemical reaction. Two catalysts are tested to
see which will most effectively increase the rate of hydrogen peroxide decomposition. Hydrogen
peroxide decomposes into water and oxygen.
HYPOTHESIS: Catalyst A will increase the rate of reaction faster than Catalyst B.
Independent variable:
Dependent variable:


I only need # 5

Answer 1

Answer:

Hey there!

The independent variable is the two different catalysts.

The dependent variable is the rate of hydrogen peroxide decomposition.

If you need to review what independent and dependent variables are, you can go check the last question I answered, where I wrote an in-depth explanation.

Hope this helps :)
