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

Options

A. `Feoverset(dilH_(2)SO_(4))rarrFeSO_(4)overset(H_(2)SO_(4).O_(2))rarrFe_(2)(SO_(4))_(3)overset("heat")rarrFe`
B. `Feoverset(O_(2),"heat")rarrFeOoverset(dilH_(2)SO_(4))rarrFeSO_(4)overset("heat")rarrFe`
C. `Feoverset(Cl_(2),"heat")rarrFeCl_(3)overset("heat, air")rarrFeCl_(2)overset(Zn)rarrFe`
D. `Feoverset(O_(2),"heat")rarrFe_(3)O_(4)overset(Co,600^(@)C)rarrFeOoverset(CO, 700^(@)C)rarrFe`

Answer

D

Explanation

(d) The correct reaction are as follows
(a) `Fe+H_(2)SO_(4)rarrFeSO_(4)+H_(2),H_(2)SO_(4)+2FeSO_(4)+(1)/(2)O_(2)rarrFe_(2)(SO_(4))_(3)+H_(2)O`
`Fe_(2)(SO_(4))_(3)overset(Delta)rarrFe_(2)O_(3)(s)+3SO_(3)uarr" (This is given Wrongly)"`
(b) `Feoverset(O_(2))underset(Delta)rarr("it could also be "Fe_(2)O_(3) or Fe_(3)O_(4))`
`FeO+H_(2)SO_(4)rarr FeSO_(4)+H_(2)O`
`2FeSO_(4)overset(Delta)rarr Fe_(2)O_(3)+SO_(2)+SO_(3)`
`Feoverset(Delta)underset(Cl_(2))rarrFeCl_(3)overset(Delta)underset(air)rarr" no reaction "("it cannot give "FeCl_(2))`
(d) `Feoverset(O_(2))underset(Delta)rarr Fe_(3)O_(4)overset(CO)underset(600^(@)C)rarr FeOoverset(CO)underset(700^(@)C)rarrFe" The is correct."`
