The Arrhenius equation online calculator


Online calculator which helps you calculate the Arrhenius equation.
The Arrhenius equation calculates the rate constant of reaction (k) and under conditions of a fixed temperature, a chemical reaction is possible if the molecules possess the activation energy.
The activated molecules interact through collisions, frequency of collisions (A) depends on the temperature and the chemical reaction rate depends on Ea, where Ea is the activation energy, and the greater this index, the lower the reaction rate, as the number of active interacting molecules smaller, the smaller Ea is, the faster the rate of chemical reactions, it follows that if Ea = 0, then a chemical reaction occurs almost instantaneously.
