Assertion : Extraction of iron metal fro...

Assertion : Extraction of iron metal from iron oxide ore is carried out by heating with coke.
Reason : The reaction `Fe_(2)O_(3)(s)rarrFe(s)+(3)/(2)O_(2)(g)` is a spontaneous process.

A

If both assertion and reason are true and the reason is not 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

It 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_(2)O_(3(s))rarrFe_((s))+3//2O_(2(g))` is not a spontaneous process `Fe_(2)O_(3)` is converted to `FeO` at about `400^(@)C,FeO` is converted to Fe at about `800^(@)C -1000^(@)C,`
