Le Châtelier's Principle Simulation
Production of Ammonia in the Haber Process
N2(g) + 3H2(g) ⇌ 2NH3(g) + heat
Forward reaction is exothermic. Heat acts like a product.

Explanation
The system begins at equilibrium. Change concentration, temperature, or pressure to see how the equilibrium shifts.
N2 + 3H2 ⇌ 2NH3 + heat
