Consider the reaction:
3 H2 (g) + N2 (g) ℀ 2 NH3 (g)
If this reaction is at equilibrium and the concentration of N2 is increased, what will happen to the concentration of H2 and NH3?
[H2] increases; [NH3] decreases
[H2] decreases; [NH3] decreases
It cannot be determined from the information given.
[H2] increases; [NH3] increases
[H2] decreases; [NH3] increases
