Applications of the Concept of Rate of Reaction (2)

The chemical equation showing the reaction in the Haber Process to produce ammonia

Production of ammonia using Haber Process

Contact process (1)

In the Contact Process, sulphur is burnt in an excess of air to produce sulphur dioxide gas, SO

Contact process (2)

Sulphur dioxide gas mixed with an excess of air at a temperature of 450°C

Contact Process (3)

Pressure of 1 atm is passed over vanadium(V) oxide, which functions as a catalyst, to produce sulphur trioxide gas, SO3

Contact Process (4)

Sulphur trioxide gas is dissolved in concentrated sulphuric acid to produce oleum, H2S2O7

Contact Process (5)

Oleum is diluted with water to produce concentrated sulphuric acid
