Question

This graph shows the decomposition of hydrogen peroxide as it is exposed to air. Marty claims that the graph shows that the reaction speeds up over time. Which sentence describes whether Marty is right and gives a valid reason?

Answer 1

Based on the graph, the correct option is that Marty is right because the change in concentration increases with time; option C.

What are decomposition reactions?

Decomposition reactions are reactions in which a large molecule splits or breaks down into two or more smaller molecules.

The general equation of a decomposition reaction is given below;

• A → B + C

The decomposition of hydrogen peroxide to give water and oxygen occurs when it is exposed to air.

The given graph of the decomposition of hydrogen peroxide shows that the concentration of hydrogen peroxide decreases with time.

In conclusion, the decomposition of hydrogen peroxide in the presence of air gives oxygen and water.
