An equilibrium mixture in a vessel of capacity $100 litre$ contain $1 mol$ $N_{2},$ $2 mol$ $O_{2}$ and $3 mol NO$ . Find number of moles of $O_{2}$ to be added, so that at new equilibrium the concentration of $NO$ is $0 .04 mol/lit .$ .

Options:

Answer:

Solution:

$N_{2} + O_{2} ⇌ 2 N O$
$K = \frac{3^{2}}{2 \times 1}$ …(i)
$\underset{1 - z}{N_{2}} + \underset{2 + y - z}{O_{2}} ⇌ \underset{2 z + 3}{2 N O}$
$K = \frac{(3 + 2 z)^{2}}{(2 + y - z) (1 - z)}$ …(ii)
Given, $3 + 2 z = 4$
$z = \frac{1}{2}$
(i) = (ii)
$y = \frac{101}{18}$
