`200ml` of a gaseous mixture containing `CO,CO_(2)` and `N_(2)` on complete combusion in just sufficient amount of `O_(2)` showed contration of `40ml`. When the resulting gases were passed through `KOH` solution it reduces by `50%` then calculate the volume ratio of `V_(co_(2)): V_(CO): V_(N_(2))` in original mixture .

A

`4:1:5`

B

`2:3:5`

C

`1:4:5`

D

`1:3:5`

Text Solution

Verified by Experts

The correct Answer is:
C
`{:(,N_(x)O_(y),+,yH_(2),rarr,(x)/(2)N_(2)(g),+,yH_(2)O(l)),(,10ml,,30ml,,10ml,,):}`
`10(x)/(2)=10" "implies" x=2"`
`10y=30" "implies" "y=3`
`N_(2)O_(3)`
