The Arrhenius equation is widely used in process engineering to scale kinetic data from lab to plant conditions, estimate thermal acceleration of reactions, and perform quick checks before detailed simulations. It is particularly useful for sterilisation and degradation studies in food, pharma, and petrochemical processes.
