Both $A$ and $B$

Vedclass · Answer

(C) The thermal decomposition of ferric sulphate $(Fe_2(SO_4)_3)$ yields ferric oxide and sulphur trioxide: $Fe_2(SO_4)_3 \xrightarrow{\Delta} Fe_2O_3 + 3SO_3$. The thermal decomposition of ferrous sulphate heptahydrate $(FeSO_4 \cdot 7H_2O)$ first yields anhydrous $FeSO_4$,which then decomposes to ferric oxide,sulphur dioxide,and sulphur trioxide: $2FeSO_4 \cdot 7H_2O \xrightarrow{\Delta} Fe_2O_3 + SO_2 + SO_3 + 14H_2O$. Since both reactions produce $SO_3$,the correct option is $C$.

Sulphur trioxide can be obtained by which of the following reactions?
