A mixture of $CH_{4}$ & $O_{2}$ having total volume 80 ml is sparked in an Eudiometry tube \& contraction of 40 ml is observed after cooling. What can be composition of reacting mixture?

Options:(select one or more)

Answer:

B, D

Solution:

at $t = 0$ x ml $(80 - x) ml$ 0 0

at $t = t$ 0 $(80 - x - 2 x) ml$ x ml $0 ⟵$ When $CH_{4}$ is limiting.

Now, When CH₄ is limiting

$∴ C o n t r a c t i o n = 80 - [80 - 3 x + x]$

$40 = 80 - 80 + 2 x$

$x = 20 \Rightarrow C H_{4} \to 20 m l$

$O_{2} \to 60 m l$

When O₂ is limiting:

$40 = 80 - [x - (\frac{80 - x}{2}) + \frac{80 - x}{2}]$

$x = 40 - 80 \Rightarrow 40 m l$

$C H_{4} = 40 m l; O_{2} = 40 m l$
