Statement-I : Extraction of iron metal from iron oxide ore is carried out by heating with coke.
Statement-II : The reaction `Fe_(2)O_(3) (s) overset(Delta)rarr Fe(s) +3//2O_(2)(g)` is a spontaneous process at standard condition.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
D
Extraction of iron metal from iron oxide ore is carried out by heating with coke and flux (calcium carbonate). Flux is a slag forming substance. It converts infusible impurities into fusible slag.
The reaction : `Fe_2O_(3(s)) to Fe_((s)) + 3//2 O_(2(g))` is not a spontaneous process. `Fe_2O_3` is converted to FeO at about `400^@C`. FeO is converted to Fe at about `800^@C - 1000^@C`.
