True statement, as at 300°C, FeCl3 sublimes to give gaseous dimmer as follows 2FeCl3 xrightarrow30 0° C (F e C l3)2(g)

Q. At $30 0^{o} C, F e C l_{3}$

decomposes into $F e C l_{2}$ and $C l_{2}$ .

decomposes into $F e$ and $C l_{2}$ .

sublimes go give liquid $F e C l_{3}$

sublimes to give gaseous dimmer $(F e C l_{3})_{2}$ .

True statement, as at $30 0^{\circ} C, F e C l_{3}$ sublimes to give gaseous dimmer as follows
$2 F e C l_{3} 30 0^{\circ} C (F e C l_{3})_{2} (g)$
