The zone refining method is used to obtain.......

Which of the following processes for refining of metals involves a principle of selective adsorption of the components from a mixture?

Which of the following properties of pure metal makes it more useful than the corresponding alloy?

Formation of $Ni(CO)_4$ and its subsequent decomposition into $Ni$ and $CO$ (recycled) forms the basis of the Mond process.
$Ni + 4CO$ $\xrightarrow{T_1} Ni(CO)_4$ $\xrightarrow{T_2} Ni + 4CO$
$T_1$ and $T_2$ are:

The reaction representing the $Mond$ process for metal refining is $............$.
