Vedclass · Answer

(A) The Mond process is a technique used to extract and purify nickel. In this process,impure nickel is heated in a stream of carbon monoxide $(CO)$ at $330-350 \ K$ to form a volatile nickel tetracarbonyl complex: $Ni(s) + 4CO(g) \xrightarrow{330-350 \ K} Ni(CO)_4(g)$. The volatile nickel tetracarbonyl is then subjected to higher temperatures $(450-470 \ K)$,causing it to decompose into pure nickel and carbon monoxide: $Ni(CO)_4(g) \xrightarrow{450-470 \ K} Ni(s) + 4CO(g)$.
