Question

Explain thermal dissociation and thermal decomposition reactions with examples. What is the difference between them ?

KnowledgeBoat · Accepted Answer

A reversible decomposition reaction brought about only by heat is called thermal dissociation reaction. For example, on application of heat, ammonium chloride decomposes into Ammonia and HCl: NH₄Cl NH₃ + HCl A chemical reaction in which a compound decomposes to give two new elements / a new compound & an element / two new compounds on application of heat without any recombination on cooling is called a Thermal decomposition reaction. For example, calcium carbonate decomposes to carbon dioxide and calcium oxide when heated to 1000°C CaCO₃ (s) CaO (s) + CO₂ (g) Difference between the two is that thermal dissociation is a reversible decomposition reaction whereas, thermal decomposition is an irreversible reaction.
