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 $300^{o}C, \, FeCl_{3}$ sublimes to give gaseous dimmer as follows

$2FeCl_{3}\overset{30 0^{o} C}{ \rightarrow }\left(F e C l_{3}\right)_{2}\left(g\right)$
