Which series of reactions correctly represents chemical rections related to iron and its compounds ?

Options

A. `Fe overset(Cl_(2),heat)rarr FeCl_(3) overset(heat,air) rarr FeCl_(2) overset(Zn) rarr Fe`
B. `Fe overset(O_(2).heat) rarr Fe_(3)O_(4) overset(CO,600^@C) rarr FeCl_(2) overset(CO,700^@C) rarr Fe`
C. `Fe overset(dil.H_(2)SO_(4)) rarr FeSO_(4) overset(H_(2)SO_(4),O_(2)) rarr Fe(SO_(4))_(3) overset(heat) rarr Fe`
D. `Fe overset(O_(2),heat) rarr FeO overset (dil.H_(2)SO_(4)) rarr FeSO_(4) overset (heat) rarr Fe`

Answer

B

Explanation

In `(a),FeCl_(3)` cannot be reduced when heated in air.
In `( C),Fe_(2)(SO_(4))_(3)` cannot convert to `Fe` on heating , instead oxide `(s)` will be formed.
In `(d), Fe_(2)SO_(4)` cannot convert to `Fe` on heating , instead oxide `(s)` will be formed.
Hence `(b)` is correct.
