What are thermal decomposition reactions?

Answer 1

Reactions that occur when heat triggers the breakdown of a chemical compound.

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

#2NaHCO_3(s) rightarrow CO_2(g) + H_2O(g) + Na_2CO_3(s)#

Chemical reactions known as thermal decomposition reactions, which are frequently employed in a variety of industrial processes and laboratory experiments, are those in which a material, when heated, breaks down into simpler substances. This process is brought about by the absorption of heat energy, which breaks the bonds within the molecules to form new substances.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
