Practice Problem 5

Ammonia is made from nitrogen and hydrogen by the following reversible reaction.

N₂(g) + 3 H₂(g) 2 NH₃(g)

Assume that the initial concentration of N₂ is 0.050 moles per liter and the initial concentration of H₂ is 0.100 moles per liter. Calculate the equilibrium concentrations of the three components of this reaction at 500^oC if the equilibrium constant for the reaction at this temperature is 0.040.

Answer

[NH₃] = 0.0020 M

[N₂] = 0.099 M

[H₂] = 0.097 M
