Question

The Catalyst is used to increase the dissociation of h2o2

Answer 1

Answer:

As an interesting contrast, a similar increase in the rate of decomposition of hydrogen peroxide can be achieved using an inorganic catalyst such as manganese(IV) oxide or lead(lV) oxide.

Answer 2

Manganese dioxide is used to increase the dissociation of hydrogen peroxide.

• Hydrogen peroxide decomposes or dissociates to give water and oxygen gas.
• The reaction is written as follows-
• $2H_2O_2\rightarrow 2H_2O+O_2$.
• In this reaction, if add some manganese dioxide decreases the activation energy of the reaction and the reaction occurs at a faster rate.
• Hence Manganese dioxide is used to increase the dissociation of hydrogen peroxide.
