Activation energy is the minimum energy which must be available to a chemical system with potential reactants to result in a chemical reaction.
The Arrhenius equation as it's used in chemistry is often stated according to the formula:
{tex}k = Ae^{-E_a\over RT}{/tex}
where:
- k is the rate constant
- A is an exponential factor that is a constant for a given chemical reaction, relating the frequency of collisions of particles
- the activation energy of the reaction (usually given in Joules per mole or J/mol)
- R is the universal gas constant
- T is the absolute temperature in Kelvin
