Question

By giving example define thermal dissociation reaction.

Answer 1

Thermal dissociation reaction is a chemical reaction in which a substance decomposes reversibly when the temperature is raised.

Example: $\underset{\mathrm{calcium}\mathrm{carbonate}}{\underset{}{{\mathrm{CaCO}}_3}}\rightleftarrows \underset{\mathrm{calcium}\mathrm{oxide}}{\underset{}{\mathrm{CaO}}}+\underset{\mathrm{carbon}\mathrm{dioxide}}{\underset{}{{\mathrm{CO}}_2}}$
