In Marcus theory one term in this equation is replaced by the difference of the delta G of inner sphere electron transfer and the delta G of outer sphere electron transfer.
In Marcus theory one term in this equation is replaced by the difference of the delta G of inner sphere electron transfer and the delta G of outer sphere electron transfer. One quantity in this equation is equal to the product of the steric factor and collision frequency. One modification of this equation, which uses the term "Boltzmann's constant times temperature divided by Planck's constant" as a replacement for this equation's pre-exponential factor, is named for Eyring. It states that the rate constant is proportional to the exponential of the negative of the activation energy divided by the ideal gas constant and temperature. For 10 points, name this equation which can be used to calculate the dependence of a reaction rate on temperature.
