Answer to Question #260678 in Civil and Environmental Engineering for angel

Question

What effect does MnO2 have on the equilibrium constant?

Answer 1

Manganese dioxide MnO2 catalyzes the decomposition of hydrogen peroxide to oxygen and water. Since manganese dioxide is a catalyst, it is not consumed in the reaction.

Catalysts are chemical substances that lower the activation energy of a chemical reaction and, as a result, increase the rate at which the reactants are converted into products. The catalysts used in a given reaction depends on the type of reaction.
