# Exponential Model for Arrhenius Activation Energy

Exponential Model for Arrhenius Activation Energy

At temperatures around some appropriate reference temperature , a chemical reaction’s rate constant , represented by the Arrhenius equation, can also be described by a simpler exponential model. This Demonstration converts the Arrhenius equation activation energy (in kilojoules/mole or kilocalories/mole) into the exponential model parameter (in ) for a chosen . Similarly, it converts the exponential model parameter into a corresponding activation energy as defined by the Arrhenius equation. The conversions permit using published values in software for predicting degradation and synthesis patterns written for the exponential model, or comparing calculated values with known activation energies.
