Forty millililtre of `CO` was mixed with 100 ml of `O_2` and the mixture was exploded. On cooling, the reaction mixture was shaken with `KOH` What volume of gas is left?

A

60 ml of `O_2`

B

80 ml of `O_2`

C

20 ml of `CO`

D

40 ml `CO_2`

Text Solution

Verified by Experts

The correct Answer is:
B
`CO+(1)/(2)O_2rarrCO_2`
`40 ml, 20 ml, undersetunderset(ab so rbed)(darrKOH)(40ml)`
Volume of `O_2` left `=(100-20)=80ml`
