Solution: For the reaction shown here 2NH3(g) ⇌ 3H2(g) + N2(g)the equilibrium concentrations were found to be [NH3] = 0.250 M [H2] = 0.580 M [N2] = 0.750 M What is the equilibrium constant for this reaction?

Problem

For the reaction shown here 

2NH3(g) ⇌ 3H2(g) + N2(g)

the equilibrium concentrations were found to be 

[NH3] = 0.250 M 

[H2] = 0.580 M 

[N2] = 0.750 M 

What is the equilibrium constant for this reaction?
