$2 N O C l (g) ? 2 N O (g) + C l_{2} (g)$

In an experiment 2.0 mole of NOCl was placed in a non-litre flask and the concentration of NO after equilibrium established, was found to be 0.4 mol/L. The equilibrium constant at 30°C is__________× 10^-⁴

$2 N O C l_{(g)} ? 2 N O (g) + C l_{2} (g)$

t = 0 2 mol/Lit 0 0

t_eq 2 – x x x/2

$K_{C} = \frac{{[N O]}^{2} \times [C l_{2}]}{{[N O C l]}^{2}} = \frac{x^{2} \times x}{{(2 - x)}^{2} \times 2} = \frac{x^{3}}{{(2 - x)}^{2} \times 2}$

$= \frac{0.4 \times 0.4 \times 0.4}{1.6 \times 1.6 \times 2}$ = 0.0125 = 125 × 10^-4
