Answer:
a. A thermal decomposition reaction can be defined as a decomposition reaction which is activated by thermal energy. ... A common example of a thermal decomposition reaction is provided below. CaCO3 → CaO + CO2. When heated, calcium carbonate decomposes into calcium oxide and carbon dioxide.
b. Examples of inorganic catalysts in chemical reactions include: potassium permanganate - Hydrogen peroxide will decompose into water and oxygen gas. Two molecules of hydrogen peroxide will produce two molecules of water and one molecule of oxygen.
