Consider the Following Reaction at Equilibrium

Consider the following reaction at equilibrium:
2NH₃ (g) N₂ (g) + 3H₂ (g) OH° = +92.4 kJ
Le Cha^{^}telier's principle predicts that adding N₂ (g) to the system at equilibrium will result in

A) a decrease in the concentration of NH₃ (g)
B) removal of all of the H₂ (g)
C) a lower partial pressure of N₂
D) an increase in the value of the equilibrium constant
E) a decrease in the concentration of H₂ (g)
