MCQ
What volume of dioxygen is required for complete combustion of $2\, volumes$ of acetylene gas at $NTP$ ? ................. $\mathrm{Volumes}$
- A$2$
- ✓$5$
- C$10$
- D$4$
✓
Answer
Correct option: B.
$5$
b
$\mathrm{C}_{2} \mathrm{H}_{2}+\frac{5}{2} \mathrm{O}_{2} \rightarrow 2 \mathrm{CO}_{2}+\mathrm{H}_{2} \mathrm{O}$
$\mathrm{C}_{2} \mathrm{H}_{2}+\frac{5}{2} \mathrm{O}_{2} \rightarrow 2 \mathrm{CO}_{2}+\mathrm{H}_{2} \mathrm{O}$
$1$ $vol.$ $\mathrm{C}_{2} \mathrm{H}_{2}=\frac{5}{2}\, \mathrm{vol} .$ of $\mathrm{O}_{2}$
$2 \,\mathrm{vol} . \mathrm{C}_{2} \mathrm{H}_{2}=5 \,\mathrm{vol}$ of $\mathrm{O}_{2}$
