Write the example of each catalyst that accelerates and decelerates the rate of chemical reaction along with the balanced chemical reaction.

Manganese dioxide(MnO₂) accelerates the decomposition of Hydrogen Peroxide(H₂O₂) into water(H₂O) and Oxygen(O₂).

2H₂O₂MnO₂
            ➤ 2H₂O + O₂↑

Glycerine(C₃H₅(OH)₃) decelerates the decomposition of Hydrogen Peroxide(H₂O₂) into water(H₂O) and Oxygen(O₂).

2H₂O₂Glycerine
            ➤ 2H₂O + O₂↑
