Given the reaction: N2 + O2 = 2NO for which the Keq at 2273 K is 1.2 x 10-4

MAXImum [283]

<u>Answer:</u>

(a): The expression of equilibrium constant is $K_{eq}=\frac{[NO]^2}{[N_2][O_2]}$

(b): The equation to solve the concentration of NO is $[NO]=\sqrt{K_{eq}\times [N_2]\times [O_2]}$

(c): The concentration of NO is 0.0017 M.

<u>Explanation:</u>

The equilibrium constant is defined as the ratio of the concentration of products to the concentration of reactants raised to the power of the stoichiometric coefficient of each. It is represented by the term $K_{eq}$
