Question

how can the rate of chemical reaction namely decomposition of hydrogen peroxide be increased?

Answer 1

Using a catalyst called as Manganese dioxide we increase the speed of decomposition of Hydrogen peroxide. H2O2 decomposition can be done easily by heating. But by increasing the catalyst we can decompose without heating.

Answer 2

Answer:

hope it helps

Explanation:

(i) The chemical reaction in which two or more

products are formed from a single reactant

is called a decomposition reaction. Hydrogen

peroxide decomposes into water and oxygen.

2H2

O2(l)

→ 2H2

O (l) + O2

↑

Hydrogen Oxygen

peroxide

Water

(ii) The decomposition of hydrogen peroxide into

water and oxygen takes place slowly at room

temperature. However, the rate of this chemical

reaction can be increased on adding manganese

dioxide (MnO2

) powder in it, here manganese

dioxide acts as a catalyst.
