Question

At $300^{o}C,FeC{l}_3$

• A. decomposes into $FeC{l}_2$ and $C{l}_2$ .
• B. decomposes into $Fe$ and $C{l}_2$ .
• C. sublimes go give liquid $FeC{l}_3$
• D. sublimes to give gaseous dimmer ${\left(FeC{l}_3\right)}_2$ .

Answer 1

Answer: (D)

True statement, as at $300^{o}C,FeC{l}_3$ sublimes to give gaseous dimmer as follows

$2FeC{l}_3\stackrel{300^{o}C}{\to }{\left(FeC{l}_3\right)}_2\left(g\right)$
