Factors Affecting Rate of Reaction (2)

Factor that only affects the rate of reaction involving reactants in the form of gas

Pressure

Reason for below condition " The rate of reaction for solid or liquid reactant normally not affected by pressure"

Because solids cannot be compressed and it is difficult to compress liquids

Examples of industrial processes which use high pressure to increase their rate of reaction (1)

The synthesis of ammonia by the Haber process

Examples of industrial processes which use high pressure to increase their rate of reaction (2)

Contact Process (Produces Sulphuric Acid)

The rate of reaction reactions for reaction involving gaseous reactant

The rate of reaction usually increases when pressure increases
