Answer:

The concentration of NO₂ is 0,0230M

Explanation:

The equilibrium constant, kc, express the ratio in equilibrium between products and reactants. For the reaction:

N₂O₄(g) ⇄ 2NO₂ (g) kc = 0.211 at 100°C

kc = $\frac{[NO_{2}]^2}{[N_{2}O_{4}]}$

In equilibrium:

0,211 = $\frac{[NO_{2}]^2}{[0,00251]}$

5,2961x10⁻⁴ = [NO₂]²

0,0230 M = [NO₂]
