Question

Give one example of thermal decomposition reaction?

Answer 1

Thermal decomposition reaction:

• A thermal decomposition reaction can be defined as a decomposition reaction that is activated by thermal energy.
• Such reactions are generally endothermic since energy is required to break the chemical bonds and separate the constituent elements.

For example:

${\mathrm{CaCO}}_3\left(\mathrm{s}\right)\stackrel{\mathrm{Heat}}{\to }\mathrm{CaO}\left(\mathrm{s}\right)+{\mathrm{CO}}_2\left(\mathrm{g}\right)$

Here, when CaCO₃ is heated it breakdown into two products(CaO and CO₂) which is an example of a thermal decomposition reaction.

Therefore, this is the required explanation.
