Which property of manganese dioxide helps it turn hydrogen peroxide into water faster than it would without it?

A. Manganese dioxide is an acid.
B. Manganese dioxide is a catalyst.
C. Manganese dioxide is highly reactive.
D. Manganese dioxide is used up very fast.

Answer:

B is the correct answer.

......Hopefully it it helpful.......

The property of manganese dioxide helps it turn hydrogen peroxide into water faster than it would without it is Manganese dioxide is a catalyst.

Hence, option B is correct answer.

A catalyst in a chemical reaction is substance that increases the rate of a chemical reaction.

The reaction of manganese dioxide with hydrogen peroxide is

MnO₂ + H₂O₂ → H₂O + O₂

Now, lets check all options one by one.

Option (A): Manganese dioxide is an acid.

Manganese dioxide (MnO₂) is weak acid and its solubility is very less.

So, it is incorrect option.        

Option (B): Manganese dioxide is a catalyst.

Adding a catalyst to a reaction it speeds up the rate of reaction and in the absence of catalyst the reaction proceed slowly.  

So, it is correct option.

Option (C): Manganese dioxide is highly reactive.

Manganese dioxide is unstable. Manganese dioxide is is an inorganic compound. Manganese dioxide is oxidizing agent.

So, it is incorrect option.

Option (D): Manganese dioxide is used up very fast.

Manganese dioxide acts as catalyst for decomposition of H₂O₂ that means it is not consumed in the chemical reaction.

So, it is incorrect option.

Thus, from the above conclusion we can say that Manganese dioxide is a catalyst is the property of manganese dioxide helps it turn hydrogen peroxide into water faster than it would without it.

Hence, option B is correct answer.
