The assertion is false, but the reason is true.

In the Mond's process, the decomposition of metal carbonyl compounds is an endothermic reaction, not an exothermic reaction. Metal carbonyl compounds, such as nickel tetracarbonyl (Ni(CO)4), are volatile and can decompose at high temperatures, releasing carbon monoxide gas and regenerating the pure metal.

The reason provided is accurate. The decomposition of metal carbonyl compounds in the Mond's process does release heat energy, but this heat is not utilized to aid in the purification process. Instead, external heat sources are typically required to provide the necessary temperature for the decomposition reaction to occur. The release of heat during the decomposition is a byproduct rather than a purposeful aid in the purification process.

Therefore, the assertion is false because the decomposition of metal carbonyl compounds in the Mond's process is an endothermic reaction, while the reason is true as it correctly states that the decomposition releases heat energy.
