Question

explain the term thermal decomposition giving a suitable example

Answer 1

A thermal decomposition reaction occurs when heat is applied to a compound causing it to decompose (break down) into multiple different chemical substances. An example is when baking soda (sodium bicarbonate) is heated.

Answer 2

When heat is used to break down one single compound into many different simpler substances, The reaction is termed as "Thermal Decomposition Reaction"

For example:

CaCO3(s) → CaO(s) + CO2(g)
Lime stone → Quick lime + Carbon dioxide
