Question

Manganese dioxide (MRO) is a catalyst used in the decomposition of hydrogen peroxide (H2O2) into water and oxygen,
Which of the following is the correct way to represent the reaction?​

Answer 1

Answer:

Hydrogen peroxide also decomposes in the presence of a metal oxide catalyst into water and oxygen in an exothermic reaction (eq 1). (2) Using a catalyst, such as MnO2, reduces the activation energy to ∼58 kJ/mol(1) and accelerates the decomposition over 1000 times relative to the uncatalyzed reaction.
