Write answers to the following.
How can the rate of the chemical reaction, namely, decomposition of hydrogen peroxide be increased?
Answer:
Decomposition of hydrogen peroxide is a slow process:
2H2O2(l) → 2H2O + O2↑ (slow reaction)
But we can increase the rate of reaction by using a particular catalyst, i.e., Manganese dioxide powder (MnO2).
A catalyst is a substance which increases the rate of reaction without causing any chemical change.
