(B) In the $Mond$ process,impure $Nickel$ is heated in a stream of carbon monoxide $(CO)$ to form a volatile complex,$Nickel$ tetracarbonyl.This complex is then decomposed at a higher temperature to obtain pure $Nickel$ metal.The chemical reactions are:$Ni(s) + 4CO(g) \xrightarrow{330-350 K} Ni(CO)_4(g)$$Ni(CO)_4(g) \xrightarrow{450-470 K} Ni(s) + 4CO(g)$
