Understand the concept of the equilibrium constant (K). It is a measure of the ratio of the concentration of products to reactants at equilibrium. A large K value indicates that the equilibrium favors the formation of products, while a small K value indicates that the equilibrium favors the formation of reactants.
For part (a), the equilibrium constant K is 1.0 x 10^20, which is a very large number. This suggests that the concentration of products (NO) is much greater than the concentration of reactants (N2 and O2) at equilibrium.
For part (b), the equilibrium constant K is 2.2 x 10^-22, which is a very small number. This indicates that the concentration of reactants (CO and O2) is much greater than the concentration of products (CO2) at equilibrium.
For part (c), the equilibrium constant K is 1, which means the concentrations of reactants (BrCl) and products (Br2 and Cl2) are equal at equilibrium.
Based on the analysis of the equilibrium constants, the correct answer is: a) products, b) reactants, c) equal.
