Activation Energy

The minimum energy which must be available to a chemical system with potential reactants to result in a chemical reaction.

A fire is not much more than a combination of carbon and oxygen, but the forests and coal mines of the world are not combusting at will because such a chemical reaction requires the input of a critical level of “activation energy” in order to get a reaction started. Two combustible elements alone are not enough.
