Why MNO2 is known as positive catalyst
Answers
Answer:
hey mate here is the answer....
Explanation:
Manganese dioxide (
M

O
2
) can also be called manganese (IV) oxide . This ionic compound can catalyze the decomposition of hydrogen peroxide.
Catalysts decrease the activation energy for chemical processes.

A bamboo skewer is lit on fire using a candle, then blown out. Lowering the still glowing end into the test tube where the reaction is taking place causes the bamboo to start burning again because of the oxygen which is being created by the reaction.
Answer:
Explanation:
If catalyst increases the rate of a reaction then catalyst is known as the positive catalyst & the phenomenon is known as the catalysis. 1: Decomposition of KClO3 is increased by MnO2, therefore MnO2 is a positive catalyst.
