Making fertilisers
1. Ammonia is made in the Haber process2. The raw materials are nitrogen (from
the air) and hydrogen (from natural gas)
3. The conditions needed are;• high temperatures (about 4500) • high pressures (200 atm). • iron catalyst

The Haber Process
1. The Haber process reaction is reversible2. This means that the product (ammonia)
can break down again into the reactants (nitrogen and hydrogen)

Reversible reaction
1. For a reversible reaction in a closed system, an equilibrium is reached where the rate of the forward reaction equals the rate of the reverse reaction
2. The amount of reactants and products in the equilibrium depends on the conditions
3. The equilibrium will move to reduce any changes in the reaction

1. Ammonia reacts with oxygen in the air in the presence of a hot platinum catalyst to produce nitrogen monoxide
2. The nitrogen monoxide reacts with water and more oxygen to produce nitric acid
