Vedclass · Answer

(C) The extraction of nickel is carried out by the $Mond$ process. In this process,impure nickel is heated in a stream of carbon monoxide to form volatile nickel tetracarbonyl,$Ni(CO)_4$. $Ni(s) + 4CO(g) \xrightarrow{330-350 \ K} Ni(CO)_4(g)$ This volatile complex is then subjected to higher temperatures,causing it to decompose into pure nickel and carbon monoxide. $Ni(CO)_4(g) \xrightarrow{450-470 \ K} Ni(s) + 4CO(g)$ Therefore,the process involves both the formation and thermal decomposition of $Ni(CO)_4$.
