Its basic formulation states that the rate is equal to a constant times the exponential of negative E sub a over RT.
This relation is extended by Randall-Wilkins theory and the substitution of Marcus theory into it will produce DeVault-type control coefficients. It can be used as an electronic model to predict failure mechanisms including void formation and metal migration, and is very similar to the Eyring Equation which also applies to mixed phase and condensed situations. The namesake pre-exponential factor assumes the constancy of the collision frequency and the steric factor. Its basic formulation states that the rate is equal to a constant times the exponential of negative E sub a over RT. FTP, name this equation of chemical kinetics including a term for activation energy, named for a noted Swedish chemist.
