For the following reaction, Kc = 2.7×108 at 300 K.

Question

3 H2(g) + N2(g) ⇌ 2 NH3(g)

In an experiment carried out at 300 K, the initial concentrations of H2(g) and N2(g) are each equal to 2.0 mol L−1 .

Which of the following statements about the equilibrium concentrations is correct? Note: In the statements below, << means "much less than".
a. [NH3] << [N2] ≈ [H2]
b. [H2] ≈ [N2] ≈ [NH3]
c. [H2] ≈ [N2] << [NH3]
d. [H2] << [N2] ≈ [NH3]
e. [N2] << [H2] < [NH3]
