Respuesta :

The balanced equation:
               N₂O₄(g) ↔ 2 NO₂(g)
From the equation we can write equilibrium constant expression as follows:
Keq = [NO₂]² / [N₂O₄]
So the correct exponent for N₂O₄ equal 1
The correct answer is one
 

Answer: 1

Explanation:

Equilibrium constant is the ratio of product of concentration of products to the product of the concentration of reactants each term raised to their stochiometric coefficient.

[tex]N_2O_4\rightleftharpoons 2NO_2[/tex]

[tex]K=\frac{[NO_2]^2}{[N_2O_4]^1}[/tex]

Thus the exponent for the concentration of [tex]N_2O_4[/tex] is 1.
