Question

At $300^{o}C, \, FeCl_{3}$

• A. decomposes into $FeCl_{2}$ and $Cl_{2}$ .
• B. decomposes into $Fe$ and $Cl_{2}$ .
• C. sublimes go give liquid $FeCl_{3}$
• D. sublimes to give gaseous dimmer $\left(F e C l_{3}\right)_{2}$ .

Answer 1

Answer: (D)

True statement, as at $300^{\circ}C, \, FeCl_{3}$ sublimes to give gaseous dimmer as follows
$2FeCl_{3}\xrightarrow{30 0^{\circ} C} \left(F e C l_{3}\right)_{2}\left(g\right)$
