A gaseous mixture was prepared by taking equal moles of `CO` and `N_(2)`. If the total pressure of the mixture was found to be `1` atomosphere, the partical pressure of the nitrogen `(N_(2))` in the mixture is

Options

A. 1 atm
B. 0.5 atm
C. 0.8
D. 0.9 atm

Answer

B

Explanation

Equal number of mles exert same partial pressure at same temperature and pressure . Therefore partial pressure of `N_(2)` in the mixture is 0.5 atm .
`(p_("total") = p_(1) + p_(2) , 1` atm = `2 p_(1) , p_(1) =0.5` atm )
