Vedclass · Answer

(B) The thermal decomposition of ferric sulphate is a standard laboratory method for the preparation of sulphur trioxide: $Fe_2(SO_4)_3 \xrightarrow{\Delta} Fe_2O_3 + 3SO_3$ Analysis of other options: $(A)$ $CaSO_4 + C \xrightarrow{\Delta} CaO + SO_2 + CO$ (Produces $SO_2$) $(B)$ $Fe_2(SO_4)_3 \xrightarrow{\Delta} Fe_2O_3 + 3SO_3$ (Produces $SO_3$) $(C)$ $S + 2H_2SO_4 \xrightarrow{\Delta} 3SO_2 + 2H_2O$ (Produces $SO_2$) $(D)$ $H_2SO_4 + PCl_5 \xrightarrow{\Delta} SO_3HCl + POCl_3 + HCl$ (Produces chlorosulphonic acid) Thus,$SO_3$ is obtained by heating $Fe_2(SO_4)_3$.
