A gaseous mixture was prepared by taking equal moles of CO and `N_2`. If the total pressure of the mixture was found 1 atmosphere, the partial pressure of the nitrogen `(N_2)` in the mixture is

A

0.9 atm

B

1 atm

C

0.5 atm

D

0.8 atm

Text Solution

Verified by Experts

The correct Answer is:
C
`n(CO) = n (N_(2))`
`:. P(CO) = p(N_(2)) = p`(say)
This is because partial of a gas is proportional to its moles in mixture
`:. P(C) + p(N_(2)) = 1`
`p + p = 1`
`2p = 1`
`p = 1//2 = 0.5`
`p(N_(2)) = p = 0.5` atm
