Vedclass · Answer

(A) Mond's process is a chemical vapor deposition process used for the purification of nickel $(Ni)$.In this process,impure nickel is heated in a stream of carbon monoxide $(CO)$ at $60-80 \ ^\circ C$ to form volatile nickel tetracarbonyl,$Ni(CO)_4$.$Ni(s) + 4CO(g) \xrightarrow{60-80 \ ^\circ C} Ni(CO)_4(g)$This volatile complex is then decomposed at a higher temperature $(180 \ ^\circ C)$ to obtain pure nickel.$Ni(CO)_4(g) \xrightarrow{180 \ ^\circ C} Ni(s) + 4CO(g)$Thus,the correct option is $(A)$.
