$Ni + 4 CO \xrightarrow{\Delta} Ni(CO)_4$

(A) The $Mond$ process is a technique used for the refining of $Nickel$ $(Ni)$.In this process,impure $Nickel$ is heated in a stream of $Carbon$ $monoxide$ $(CO)$ to form a volatile complex,$Nickel$ $tetracarbonyl$ $(Ni(CO)_4)$,which is then decomposed at higher temperatures to obtain pure $Nickel$.The reaction is: $Ni + 4 CO \xrightarrow{\Delta} Ni(CO)_4$.
