Answer» Correct Answer - B `N_(2)(g) + O_(2)(g) hArr 2NO(g)` `1mol e 2mol e 3mol e` `K_(c)=((3))^(2)/(1xx2)=((g)/(2))`. Let a mole of `O_(2)` is added, Then, `t=0{:(N_(2)(g),+,O_(2)(g),hArr,2NO(g)),(1"mole",,2"mole",,3"mole"),(1,,(2+a),,3),((1-x),,(2+a)-x,,(3+2x)):}` `[NO]=[(3+2x)/(100)]=0.04 , (3+2x)=4`. `2x=1, x=0.5`. `((3+2x)^2) /((1-x)(2+a-x))=(9)/(2)` `K_(c)=((4)^2))^(2)/(0.5[(1.5)-a])=(9)/(2)` `=(16)/(0.5(1.5+a))=(9)/(2)` `=(35)/(4.5)=[1.5+a]` `7.11=1.5+a`. `a=(101)/(18)=5.61` |
