Vedclass · Answer

(C) The Mond process is used for the refining of nickel.Nickel is heated with $CO$ at a lower temperature $(T_1 = 50\,^{\circ}C)$ to form highly volatile nickel tetracarbonyl,$Ni(CO)_4$.This complex is then decomposed to pure nickel at a higher temperature $(T_2 = 230\,^{\circ}C)$.The reaction is: $Ni + 4CO$ $\xrightarrow{50\,^{\circ}C} Ni(CO)_4$ $\xrightarrow{230\,^{\circ}C} Ni + 4CO$.Thus,$T_1$ and $T_2$ are $50\,^{\circ}C$ and $230\,^{\circ}C$ respectively.

The formation of $Ni(CO)_4$ and its subsequent decomposition into $Ni$ and $CO$ forms the basis of the Mond process.
$Ni + 4CO$ $\xrightarrow{T_1} Ni(CO)_4$ $\xrightarrow{T_2} Ni + 4CO$
What are the values of $T_1$ and $T_2$?
