Hydrogen peroxide decomposes to form water and oxygen

Click For Summary
SUMMARY

Hydrogen peroxide decomposes into water and oxygen, a reaction that occurs slowly under normal conditions. The addition of manganese oxide (MnO2) acts as a catalyst, significantly increasing the reaction rate. However, simply doubling the amount of MnO2 does not necessarily lead to a proportional increase in the reaction rate due to the inherent limitations of catalysts. Excessive amounts of catalyst can lead to "poisoning," which diminishes effectiveness, suggesting the need for alternative catalysts or co-catalysts for optimal results.

hydrogen peroxide decomposes to form water and oxygen. Its a slow rate of reaction and it takes time to decompose. So we faster the rate of reaction by adding manganese oxide which is a catalyst its function is to faster the rate of reaction .

my question is if we doubled the amount of MnO2 does the rate of reaction increase more or not?

It may be, but there is a limit for catalysts. Indeed, the term "catalyst" indicates that a very small amount is enough to produce a faster reaction, so in my opinion, doubling the catalyst amount will not give the desired result, even "poisoning" may occur. Alternatively, look for another catalyst or a co-catalyst for a synergistic reaction.
