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.
What is Catalyst in a chemical reaction ?
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 (MnOâ‚‚) is weak acid and its solubility is very less.
So, it is incorrect option. Â Â Â Â
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. Â
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 Hâ‚‚Oâ‚‚ 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.
