उत्तर
Thermal decomposition and thermal dissociation.
- Thermal decomposition: “A chemical reaction in which a compound decomposes into two new substances by heat.” It is not a reversible reaction.
\[\ce{CaCO3->[\Delta]CaO + CO2}\] - Thermal dissociation: “Is decomposition of a compound into two or more new substances by heat energy.” It is a reversible reaction.
\[\ce{NH4Cl⇌[heat][cool]NH3 + HCl}\]
