In the given case, the correct choice would be - The concentration of reactants exceeds the concentration of products

The equilibrium constant is simply a measure of the position of the equilibrium in terms of the concentration of the products and of the reactants in a given equilibrium reaction.

  • In other words, the equilibrium constant tells you if you should expect the reaction to favor the products or the reactants at a given temperature.

This is done by comparing the equilibrium concentrations and the stoichiometric coefficients of the chemical species involved in the reaction.

For your equilibrium reaction

2NO g ⇌ N2 g + O2   and K of [NO] = [tex]2 \times 10^{-9}[/tex]

the equilibrium constant takes the form

K = [tex]\frac {[NO]}{[N_2] [O_2]}[/tex]

K of products is very small than the k of reactants.

Thus, In the given case, the correct choice would be - The concentration of reactants exceeds the concentration of products
