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.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion
B. If both assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false

Answer

D

Explanation

Extraction of iron metal from iron oxide ore is carried out by heating with coke and flux (calcium carbonate). Flux is slag forming substance. It converts infusible impurities into fusible slag.
The reaction : `Fe_(2)O_(3(g))rarrFe_(r)+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`
