Justify that the following reactions are redox reactions : Fe_(2)O_(3)(s)+3CO(g)to2Fe(s)+3CO_(2)(g)

Justify that the following reactions are redox reactions : Fe_(2)O_(3

1.	Justify that the following reactions are redox reactions : Fe_(2)O_(3)(s)+3CO(g)to2Fe(s)+3CO_(2)(g)
Answer» Solution :`overset(+3)(Fe_(2))overset(-2)(O_(3))(s)+overset(+2-2)(3CO)(g)to2overset(0)Fe(s)+overset(+4-2)(3CO_(2))(g)` In this REACTION, `Fe_(2)O_(3)` is UNDERGOING reduction because the O.S. of Fe is decreasing from +3 ( in `Fe_(2)O_(3)` ) to 0 (in Fe), whereas CO is undergoing oxidation as the O.S. of carbon increases from +2 (in CO) to +4 ( in `CO_(2)` ). Hence, it is a REDOX reaction.
