Which series of reactions correctly represents chemical relations related to iron and its compound?

Multiple Choice Options

  • A Fe ⟶dil.H2SO4 FeSO4 ⟶H2SO4,O2 Fe2(SO4)3 ⟶heat Fe
  • B Fe ⟶O2,heat FeO ⟶dil.H2SO4 FeSO4 ⟶heat Fe
  • C Fe ⟶Cl2,heat FeCl3 ⟶heat,air FeCl2 ⟶Zn Fe
  • D Fe ⟶O2,heat Fe3O4 ⟶CO,600oC FeO ⟶CO,700oC Fe

Step-by-Step Verified Solution

In equation

(i) Fe2(SO4)3

and in equation

(ii) Fe2(SO4)3

on decomposing will form oxide instead of Fe.

The correct sequence of reactions is

Fe⟶O2,heatFe3O4⟶Co,600∘C

Fe2(SO4)3⟶ΔFe
