Arrhenius equation (for reliability) - JEDEC

Rate Determination and Activation Energy. An important part of the kinetic analysis of a chemical reaction is to determine the activation energy, E a. Activation energy can be defined as the energy necessary to initiate an otherwise spontaneous chemical reaction so that it will continue to react without the need for additional energy.

THE EFFECT OF TEMPERATURE ON REACTION RATES

The reaction rate or rate of reaction is the speed at which reactants are converted into products. For example, the oxidative rusting of iron under Earth's atmosphere is a slow reaction that can take many years, but the combustion of cellulose in a fire is a reaction that takes place in fractions of a second.
