THE EFFECT OF PRESSURE ON REACTION RATES ARE

This page describes and explains the way that changing the pressure of a gas changes the rate of a reaction.

The facts

What happens?

Increasing the pressure on a reaction involving reacting gases increases the rate of reaction. Changing the pressure on a reaction which involves only solids or liquids has no effect on the rate.

An example

In the manufacture of ammonia by the Haber Process, the rate of reaction between the hydrogen and the nitrogen is increased by the use of very high pressures.

In fact, the main reason for using high pressures is to improve the percentage of ammonia in the equilibrium mixture, but there is a useful effect on rate of reaction as well.

Higher temperature = molecules move around faster. and vice versa.
