Expert Answer:

Any process of decomposition by heat is called thermal decomposition. A thermal decomposition may be reversible or irreversible reaction.

Reversible thermal decomposition reactions, i.e. in which the prodcuts of decomposition can re-unite to form the original substance when the agent (heat) which brings about the decomposition is withdrawn are called thermal dissociation.
Thus, thermal dissociation is a special case of thermal decomposition.
