4.Ni(CO)4 can be prepared by passing carbon monoxide over nickel in the temperature range of *
Answers
Answer:
At 323 K, carbon monoxide is passed over impure nickel. On moderate heating, such as contact with a hot glass surface, Ni(CO)4 decomposes back to carbon monoxide and nickel metal. These two reactions form the basis for the Mond process for the purification of nickel.

Highlights
•
Among the various transitional metal oxide catalysts the nickel oxide (NiO) is one of the best catalysts for CO oxidation at a lower temperature.
•
The performances of NiO nanoparticles are highly dependent on the crystallite size, surface area and pore volume of the catalysts.
•
The unique Ni0, Ni2+ and Ni3+ species for the nickel-containing samples are make them better catalytic activity.
