# Arrhenius Equation Calculator

The Arrhenius equation is used to calculate the value of constant K at various temperatures and also the activation energy of a reaction. Higher the temperature, the probability that two molecules will collide is higher which increases kinetic energy. This kinetic energy has an effect on the activation energy of the reaction. The activation energy is the amount of energy required to ensure that a reaction happens. This Arrhenius equation calculator calculate rate constant of reaction with the effect of temperature.

## Calculate Rate Constant of Reaction

Arrhenius showed that the rate constant (velocity constant) of a reaction increases exponentially with an increase in temperature. In Arrhenius equation, 'A' is called the 'pre-exponent factor' or the 'frequency factor' and EA is the activation energy of the chemical process (reaction).
