Vedclass · Answer

(C) The correct answer is $Ni$.In the Mond process,impure nickel $(Ni)$ is heated in a stream of carbon monoxide $(CO)$ at $330-350 \ K$ 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 decomposed at a higher temperature $(450-470 \ K)$ to obtain pure nickel metal.$Ni(CO)_4(g) \xrightarrow{450-470 \ K} Ni(s) + 4CO(g)$
