write factors which affect the rate of reaction .how can the rate of chemical reaction ,namely,decomposition of hydrogen peroxide be increased
Answers
Answer:
By using the Catalyst called as Manganese dioxide we an increase the speed of decomposition of Hydrogen peroxide. Hydrogen Peroxide is normally used for dressing the wounds and cuts. Decomposition of H2O2 can be done easily by heating. But by adding catalyst we can decompose it without heating.

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.
