If density of a gaseous mixture of dinitrogen tetroxide (N_(2)O_(4)) and nitrogen dioxide (NO)_(2) is 2.5 gm/L at 127^(@)C and 1 atm pressure. [R=0.08 atm lit/mole-k] K_(p) for N_(2)O_(4)(g)hArr2NO_(2) is:

Answer»

`0.90`
0.09
`9.0`
0.009

Solution :`N_(2)O_(4)(G)hArr2NO_(2)(g)`
0.74 atm 0.26atm
`k_(p)=((0.26)^(2))/(0.74)=0.091`
`k_(p)=0.09`
