Solution

The correct option is C $F e_{2} (S O_{4})_{3} Δ \to$
(A) $S + H_{2} S O_{4} △ - \to S O_{2} + H_{2} O$

(B) $H_{2} S O_{4} + P C l_{5} △ - \to P O C l_{3} + H S O_{3} C l + H C l$

(C) $2 C a S O_{4} + C △ - \to 2 C a O + 2 S O_{2} + C O_{2}$

(D) $F e_{2} (S O_{4})_{3} △ - \to F e_{2} O_{3} + 3 S O_{3}$

Sulphur trioxide is obtained in option D only.

$∴$ , answer is option D.
