Question

What is role of MnO2 (Maganese dioxide) in the decomposition of KC1O3 (Potassium chlorate)? ​

Answer 1

Explanation:

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
