Formation of Ni(CO)4 and subsequent its ...

Formation of `Ni(CO)_4` and subsequent its decomposition into Ni and CO (recycled) makes the basis of Mond's process
`Ni + 4CO overset(T_1)(rarr)Ni(CO)_4 overset(T_2)(rarr)Ni + 4CO`
`T_1 and T_2` are

A

`100^@C, 50^@C`

B

`50^@C, 100^@C`

C

`50^@C, 220^@C`

D

`230^@C, 50^@C`

Text Solution

Verified by Experts

The correct Answer is:
C
`underset("impure")(Ni)(s)+4CO(g) overset(50-60^@C)(rarr)Ni underset("Volatile")((CO)_4)(g) overset(150 - 180^@C)(rarr) underset("pure")(Ni (S)) + underset("recycled")(4CO(g))`
