Which statement is true for the following reaction at equilibrium at 25 C?
N₂(g) + O₂ (g) ⇌ 2NO(g) ;K = 4.1 × 10^-31

Question

Which statement is true for the following reaction at equilibrium at 25 C? N₂(g)+ O₂ (g)⇌ 2NO(g);K = 4.1 × 10^-31

Quizplus · Accepted Answer

At equilibrium, the concentrations of all species are balanced. From the given equilibrium constant, we can infer that the concentrations of N₂ and O₂ are higher than that of NO since the equilibrium constant expresses the ratio of the product of concentrations of products to that of reactants. The statement about the rate of the reaction cannot be inferred from the given information. It can only be inferred that the forward reaction is not favored based on the low value of the equilibrium constant. Therefore, the best answer is B.
