Question

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

Answer 1

Hey there!

From the Arrhenius equation we came to know that the rate of a chemical reaction is equal to Ae^-( E÷RT). Where A is frequency factor, E is activation energy,T is temperature . So if we increase the temparature of the reaction the rate of the reaction will also increase.

For decomposition of hydrogen peoxide that’s also hold true . We have to slightly warmed it and also we can use MnO2 to increase the decomposition.


Hope it help

Answer 2

Answer:

Explanation:

(i) The chemical reaction in which two or more

products are formed from a single reactant

is called 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.
