BRAINCAKEEquilibrium Reactions in Industry
Some industrial processes involve reversible reactions. It is important for the yield to be as high as possible. Le Chatelier's principle can be used to find the best conditions for a high yield
Low temperatures whilst they may improve the yield of exothermic reactions will mean the reaction progresses more slowly.

Key terms in this lesson
- Exothermic
- Describes a reaction in which energy is transferred from the system to the surroundings, so the enthalpy change is negative.
- Catalyst
- A substance that increases the rate of a chemical reaction without being used up, by providing an alternative reaction pathway with a lower activation energy.
- Le Chatelier's principle
- The principle that when a system at equilibrium is subjected to a change, the system readjusts to minimise the effect of that change.
