Question

A 100-mL reaction vessel initially contains 2.60 × 10-2 moles of NO and 1.30 × 10-2 moles of H2. At equilibrium, the concentration of NO in the vessel is 0.161 M. At equilibrium the vessel also contains N2, H2O, and H2. What is the value of the equilibrium constant Kc for the following reaction?

2H₂ ?(g) + 2NO (g) = 2H2?O (g) + N₂ ?(g)
