Solution
Thermal decomposition and thermal dissociation.
Decomposition of a compound on heating into two elements or element and compound or into two new compounds. It is an irreversible reaction.
Thermal dissociation is the decomposition of a substance into two or more simpler substances on heating but the reaction is reversible.
