What is arrehenius equation and why it is used?

Swedish chemist Svante Arrhenius gave the Arrhenius equation. Until 1899, it was not clear why the rate of reaction doubled for a 10-degree rise in most of the chemical reactions. After the Arrhenius equation is discovered, the problem is solved as it explains the relation between the temperature and rate of reaction.

k=Ae−Ea/RT

where k represents the kinetic reaction rate

Ea is the activation energy

R represents the universal gas constant and

T is the absolute temperature.

After solving the above equation, it gives another useful equation, which is:

ln(k)=ln(ko)−Ea/RT
