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 500oC if the equilibrium constant for the reaction at this temperature is 0.040.


[NH3] = 0.0020 M

[N2] = 0.099 M

[H2] = 0.097 M
