Answer:
Step-by-step explanation:
Hydrogen peroxide is a harmful chemical which is broken down into oxygen and water by the catalase enzyme. The oxygen gas is released in to the air for next two minutes till reaches a steady rate and hence decrease further in an hour.
The speed with which a catalase decompose hydrogen peroxide is
times per second
In absence of catalase, H2O2 will be decomposed at a rate slower by
times
