Hydrogen peroxide decomposes to form water and oxygen

  1. Jan 14, 2005 #1
    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.
