Question

Mno2 is used for decomposition of potassium chlorate. Give reason??

Answer 1

Answer:

Manganese dioxide is a very effective catalyst for the decomposition of potassium chlorate. It allows the decomposition to occur at a lower temperature. The potassium chlorate still must be heated to release oxygen, but to lesser degree than if no catalyst were used.

Answer 2

Answer:

because if we try to decompose potassium chlorate without any catalyst it should be heated to a very high temperature,that can't be possible,so it's better to add MnO2 to decompose it at low temperature
