The Arrhenius equation is a mathematical relationship that describes the temperature dependence of reaction rates in chemical reactions. It is given by the equation:
k = Ae^(-Ea/RT)
where:
- k is the reaction rate constant
- A is the pre-exponential factor or pre-exponential rate constant
- Ea is the activation energy
- R is the gas constant (8.314 J/(mol·K))
- T is the temperature in Kelvin
The Arrhenius equation suggests that as temperature increases, the reaction rate constant also increases. It quantifies the relationship between temperature and reaction rate, allowing scientists to determine how changing temperature affects the rate of a chemical reaction.
