The gases \( A, B, C \) and \( D \) are respectively
- A \( \mathrm{Cl}_{2}, \mathrm{ClF}_{3}, \mathrm{UF}_{6}, \mathrm{ClF} \)
- B \( \mathrm{O}_{2}, \mathrm{O}_{2} \mathrm{~F}_{2}, \mathrm{U}_{2} \mathrm{O}_{3}, \mathrm{OF}_{2} \)
- C \( \mathrm{Cl}_{2}, \mathrm{ClF}, U \mathrm{~F}_{6}, \mathrm{ClF}_{3} \)
- D \( \mathrm{O}_{2}, \mathrm{OF}_{2}, \mathrm{U}_{2} \mathrm{O}_{3}, \mathrm{O}_{2} \mathrm{~F}_{2} \)
Answer & Solution
Correct Answer
(A) \( \mathrm{Cl}_{2}, \mathrm{ClF}_{3}, \mathrm{UF}_{6}, \mathrm{ClF} \)
Step-by-step Solution
Detailed explanation
\( \mathrm{MnO}_{2}+4 \mathrm{HCl}_{-}>\underset{(A)}{\Delta} \mathrm{Cl}_{2}(g)+\mathrm{MnCl}_{2}+2 \mathrm{H}_{2} \mathrm{O} \)
\( \mathrm{Cl}_{2}(g)+3 \mathrm{~F}_{2} \) (excess) \( \quad{ }_{573 \mathrm{~K}}^{(A)} \rightarrow 2 \mathrm{ClF}_{3}(g) \)
\( \mathrm{Cl}_{2}(g)+3 \mathrm{~F}_{2} \) (excess) \( \quad{ }_{573 \mathrm{~K}}^{(A)} \rightarrow 2 \mathrm{ClF}_{3}(g) \)
