`N_(2)` exerts a pressure of 0.987 bar. The mole fraction of `N_(2)` ia `(K_(H)=74.48 k `bar)

A

`7.648 xx 10^(-3)`

B

`9.87 xx 10^(-5)`

C

`1.3 xx 10^(-5)`

D

`2.6 xx 10^(-5)`

Text Solution

Verified by Experts

The correct Answer is:
C
`P_(N2)=K_(H) xx X_(N2)`
`:. X_(N2)=P_(N2)/K_(H)=(0.987"barr")/(76480"bar")=1.29 xx 10^(-5)`
