Le Chatelier's Principle for concentration changes

Equilibrium shifts to oppose the concentration change

Effect when concentration of substance is increased

Equilibrium shifts to reduce that substance's concentration

Effect when concentration of substance is decreased

Equilibrium shifts to increase that substance's concentration

Effect of increasing NH3NH_3 concentration on equilibrium

Shifts left to reduce excess NH3NH_3

Result when NH3NH_3 concentration increased (on N2N_2 & H2H_2)

Concentrations of N2N_2 and H2H_2 increase

Effect of decreasing NH3NH_3 concentration on equilibrium

Shifts right to produce more NH3NH_3

Result when NH3NH_3 concentration decreased

More ammonia is produced
